Special Issue Information

Dear Colleagues,

Climate change exacerbates resources and energy crises, posing a critical challenge to global economy prosperity, environmental sustainability, and public health. As the key element of accelerating the rate of reactions, catalysis is currently indispensable across various environmental and industrial processes, including renewable energy production, the synthesis of valuable chemicals, and environmental remediation. Thus, catalysis stands at the forefront of sustainable innovation, serving as a pivotal tool for human society in the pursuit of a cleaner, more efficient, and sustainable future.

The focus of this Special Issue is to discuss and showcase cutting-edge research and breakthroughs in catalytic science and engineering, highlighting their profound implications for addressing key challenges in environmental sustainability and resource circularity. Topics of interest include, but are not limited to, the following:

  • Catalytic solutions for air and water purification;
  • Catalytic processes for renewable energy conversion and storage;
  • Catalytic technologies for carbon capture and utilization;
  • Computational modeling and simulation of catalytic systems;
  • Catalysis for biomass conversion and biofuel production;
  • The integration of catalysis with emerging technologies (e.g., artificial intelligence, biotechnology);
  • Sustainable approaches to chemical synthesis and manufacturing;
  • Advances in catalytic materials and synthesis strategies to address the challenges of catalyst stability, selectivity, and recyclability in practical application.

We invite researchers, scientists, and engineers from academia, industry, and government laboratories to contribute original research articles, reviews, and perspectives to this Special Issue. Submissions should present significant advancements in the understanding, design, and application of catalytic processes with a clear emphasis on sustainability.

Together, let us explore developments in advanced catalysis, foster the future of catalysis, and pave the way towards a cleaner, greener, more sustainable, and more prosperous tomorrow.

In this work, ceramic monolithic catalyst carriers based on zirconium dioxide (ZrO2) were produced using fused filament fabrication (FFF). The active catalyst components were deposited on the resulting carriers using the wet impregnation method. The activity of the prepared monolithic catalysts was evaluated by catalytic oxidation of a mixture of aromatic volatile organic compounds: benzene, toluene, ethylbenzene, and o-xylene (BTEX). The efficiency of the prepared monolithic catalysts was investigated as a function of the geometry of the monolithic carrier (ZDP, Z, and M) and the chemical composition of the catalytically active component (MnFeOx, MnCuOx, and MnNiOx) during the catalytic oxidation of BTEX compounds. The mechanical stability of the catalyst layer and the dimensional stability of the 3D-printed monolithic catalyst carriers were investigated prior to the kinetic measurements. In addition, thorough characterization of the commercial ZrO2-based filament was carried out. The results of the efficiency of the prepared monolithic catalysts for the catalytic oxidation of BTEX showed that the 3D-printed model M, which contained MnFeOx as the catalytically active component, was the most successful catalyst for the oxidation of BTEX compounds. The mentioned catalyst enables the catalytic oxidation of all components of the BTEX mixture (>99% efficiency) at a temperature of 177 °C. Full article

In this study, potassium peroxymonosulfate was added to an electrolytic cell with an iron anode to achieve the dual flocculation and sulfate-radical-driven oxidative degradation of organic matter in shale gas flowback wastewater. The effects of current density, solution pH, and potassium peroxymonosulfate concentration on organic matter degradation were investigated. The results showed that chemical oxygen demand (COD) removal reached 93.4% at a current density of 40 mA/cm2, pH 7, and a potassium peroxymonosulfate concentration of 1500 mg/L, surpassing the efficiency of single electroflocculation (82.4%). The characterization of the coupled electroflocculation and peroxymonosulfate system confirmed the production of sulfate radicals and identified Fe2O3 as the primary final product in the treated wastewater. The introduction of sulfate significantly enhanced organic matter degradation, accelerated the reaction rate and improved the overall efficiency of the treatment process. This study offers valuable insights into the chemical synergistic treatment approach and its potential applications in organic wastewater treatment. Full article

Two-dimensional (2D) materials have emerged as a frontier in materials science, offering unique properties due to their atomically thin nature. Among these materials, bismuthene stands out due to its exceptional optical, electronic, and catalytic characteristics. Bismuthene exhibits high charge carrier mobility, stability, and a tunable bandgap (0.3–1.0 eV), making it highly suitable for applications in transistors, spintronics, biomedicine, and photocatalysis. This work explores the so far reported synthesis methods for obtaining 2D bismuthene, including bottom-up approaches like chemical vapor deposition and molecular beam epitaxy, and top-down methods such as liquid-phase exfoliation and mechanical exfoliation. Recent advancements in understanding 2D bismuthene structural phases, electronic properties modulated by spin-orbit coupling, and its potential applications in next-generation photocatalysts are also reviewed. As is retrieved by our literature review, 2D bismuthene shows great promise for addressing significant environmental challenges. For instance, in CO2 reduction, integrating bismuthene into 2D/2D heterostructures enhances electron transfer efficiency, thereby improving selectivity toward valuable products, such as CH4 and formic acid. In organic pollutant degradation, bismuth subcarbonate (Bi2O2CO3) nanosheets, obtained from 2D bismuthene, have demonstrated high photocatalytic degradation of antibiotics under visible light irradiation, due to their increased surface area and efficient generation of reactive species. Moreover, bismuthene-based materials exhibit potential in the photocatalytic water-splitting process for hydrogen production, overcoming issues associated with UV-light dependence and sacrificial agent usage. This review underscores the versatile applications of 2D bismuthene in advancing photocatalytic technologies, offering insights into future research directions and potential industrial applications.
