Special Issue Information

Dear Colleagues,

The issue of energy shortage and environmental crisis is becoming increasingly serious due to the economy's and society's rapid expansion. Developing green and renewable technologies for environmental remediation and energy production is critical to solving these problems. Nanostructured catalysts have attracted worldwide attention for water splitting, CO2 reduction, N2 reduction, and degradation of organic pollutants via photochemical, electrochemical, and photoelectrochemical strategies. The catalytic reactivity of catalysts is critically affected by their electronic and surface atomic structures, which depend strongly on their nanostructure. Therefore, the regulation of the structure of the catalysts is one of the best ways to modulate the catalytic properties. This Special Issue, “Advances in Nanostructured Catalysts for Energy and Environmental Applicationsaims to promote advances in synthetic strategies of nanostructured catalysts, crystal facet engineering, heterostructure, band gap engineering, morphology tailoring, plasmonic coupling, co-catalyst loading, and other aspects for energy and environmental applications, such as photo-/electro-/photoelectro-chemical water splitting for hydrogen and oxygen, reduction of CO2 and N2 into value-added chemicals, photodegradation of organic pollutants, anti-corrosion, etc. In this Special Issue, original research articles and reviews are welcome. We look forward to receiving your contributions and believe that we may open up new creative viewpoints and advance interdisciplinary cooperation in these research areas.

Photoanodes with ample visible-light absorption and efficient photogenerated charge carrier dynamics expedite the actualization of high-efficiency photoelectrochemical water splitting (PEC-WS). Herein, we fabricated the heterojunction nanostructures of In2S3/MoS2 on indium-doped tin oxide glass substrates by indium sputtering and sulfurization, followed by the metal–organic chemical vapor deposition of 2D MoS2 nanosheets (NSs). The photocurrent density of In2S3/MoS2 was substantially enhanced and higher than those of pristine In2S3 and MoS2 NSs. This improvement is due to the MoS2 NSs extending the visible-light absorption range and the type-II heterojunction enhancing the separation and transfer of photogenerated electron–hole pairs. This work offers a promising avenue toward the development of an efficient photoanode for solar-driven PEC-WS. Full article

Hydrogen has garnered considerable attention as a promising energy source for addressing contemporary environmental degradation and energy scarcity challenges. Electrocatalytic water splitting for hydrogen production has emerged as an environmentally friendly and versatile method, offering high purity. However, the development of cost-effective electrocatalytic catalysts using abundant and inexpensive materials is crucial. In this study, we successfully synthesized nitrogen-doped Co6Mo6C supported on nitrogen-doped graphene (N-Co6Mo6C/NC). The catalyst exhibited high performance and durability in alkaline electrolytes (1.0 M KOH) for hydrogen evolution, showcasing an overpotential of 185 mV at a current density of 100 mA cm−2 and a Tafel slope of 80 mV dec−1. These findings present a novel avenue for the fabrication of efficient bimetallic carbide catalysts. Full article
