Photocatalytic degradation of pollutants have a high potential for sustainable and renewable uses. TiO2 is a widely studied photocatalyst due to its high chemical and photochemical stability and wide range of applications. However, the wide band gap and low capacity of photo-induced charge separation provide lower catalytic activity; thus, improvement of these properties must be found. The doping of TiO2 with other elements, such as carbon nanoparticles (CNP) in a quantum dot form, offers a promising pathway to improve the aforementioned properties. In addition, in situ doping methods should be investigated for practical scalability, as they offer the advantage of integrating dopants directly during material synthesis, ensuring a more uniform distribution and better interaction between the dopant and the host material, in turn leading to more consistent photocatalytic properties. Current technologies primarily involve nanoparticle combinations. This work focuses on the development of a novel in situ synthesis methodology by the introduction of three different graphene-based quantum nanodots into anodic TiO2 and the following investigation of structural, morphological, and photocatalytic properties. Results indicate that the introduction of CNP allows for the shift of a set of parameters, such as the optical band gap, increased photo-induced charge carrier density of TiO2/CNP composite, and, most importantly, the change of crystalline phase composition depending on added CNP material. Research indicates that not only a higher concentration of added CNP enhances higher photocatalytic activity as tested by the degradation of methylene blue dye, but also the type of CNP determines final crystalline phase. For the first time brookite and rutile phases were obtained in anodic titania synthesized in inorganic electrolyte by introducing hydrothermally treated exfoliated graphene. Full article

Some copper-based metal–organic frameworks show promise for use as electrocatalysts because they allow for an electrode configuration in which copper species with redox and electron-conducting properties are immobilized in a three-dimensional arrangement. This work shows that the synthesis of copper terephthalates (Cu-BDCs) can lead to rigid structures of the copper hydroxyterephthalate-type or flexible structures that are isoreticular to the MOF-2 type, depending solely on the synthesis route. Here, a detailed analysis of the syntheses of the crystals is carried out employing protocols with different solvents as well as conventional or microwave-assisted solvothermal methods. All solids were fully characterized by a combination of characterization techniques, such as FE-SEM, T-XRD, TGA, and FTIR, and their electrochemical redox responses were also evaluated by cyclic voltammetry. A correlation between the Cu-BDCs structures and their electrochemical behaviors was established and a new version of an electroactive copper hydroxyterephthalate was synthesized by a microwave method in 3 h with a dimethylformamide-free protocol. This Cu-BDC was obtained as dispersed nanoflakes with a high amount of copper sites and the capacity to be reversibly electroreduced-oxidized and showed catalytic activity in the oxygen reduction reaction (ORR).

Developing efficient transition metal oxide electrodes is essential to energy conversion and storage. In this work, flower-Like FeCo2O4 nanosheets supported on Ni foam were synthesized by facile hydrothermal and calcination treatment. Various temperatures influence the morphologies and oxygen evolution reaction activities. Especially, FeCo2O4/NF-120 °C catalysts showed the best oxygen evolution reaction (OER) activity due to the fact that 3D Ni foam provided good conductive substrate-forming FeCo2O4 nanosheets, which enhanced the electrochemical stability and facilitated the transport of electrolyte and release of oxygen. In addition, the synergistic effect between Fe and Co also enhanced active sites and promoted the OER catalytic performance. The flower-like FeCo2O4/Ni electrodes showed a low overpotential of 124 and 339 mV at the current density of 10 and 50 mA cm−2 for OER, respectively. Also, they displayed a low tafel slope of 43.78 mV dec−1 and good stability in alkaline electrolyte. This research could promote the design of low-cost electrocatalysts for OER. Full article

As the core component of solid-state lithium-ion batteries (SSLIBs), the bottleneck of solid-state electrolyte is to achieve fast lithium-ion transport, high electrochemical stability, and mechanical flexibility. Polymer electrolytes offer the possibility of constructing solid-state electrolytes with the above features due to their excellent molecular designability. This preview highlights novel mesogenic (or liquid crystal)-containing polymer electrolytes (MPEs) exhibiting a combination of high ionic conductivity, high electrochemical stability, and mechanical flexibility. Insights into such MPEs enabling light and safe SSLIBs are also discussed. Full article

This review underscores the pivotal role that nickel-based catalysts play in advancing CO2 methanation technologies, which are integral to achieving carbon neutrality. This study meticulously examines various aspects of catalyst design, including the significance of support materials and co-catalysts in enhancing catalytic activity and selectivity. This discussion reveals that while nickel catalysts offer a cost-effective solution due to their availability and high performance, challenges such as sintering and carbon deposition at high temperatures remain. These issues necessitate the development of catalysts with superior thermal stability or those capable of maintaining high activity at lower temperatures. This review also highlights the innovative use of three-dimensional fiber deposition technology in fabricating catalysts, which has shown promising results in improving reaction efficiency and stability over prolonged operation. Moving forward, this research emphasizes the importance of optimizing catalyst structure and fabrication techniques to overcome existing limitations. The ongoing development in this field holds great promise for the industrial application of CO2 methanation, contributing significantly to global efforts in reducing greenhouse gas emissions and promoting sustainable energy use.
