The cathode is the most crucial component of the PEMFC because the most limiting in terms of performance, durability and cost. Regarding the performance, the main losses are due to the cathode because of the negative coupling between a sluggish ORR and H+ and O2 transport losses issues. Therefore, a lot of efforts were conducted on the one hand to ...

Synergistic optimization of the elementary steps of water dissociation and hydrogen desorption for the hydrogen evolution reaction (HER) in alkaline media is a challenge. Herein, the Ru cluster anchored on a trace P-doped defective TiO2 substrate (Ru/P-TiO2 ) was synthesized as an electrocatalyst for the HER; it exhibited a commercial Pt/C-like geo...

An electrochemical nitrogen reduction reaction (ENRR) is considered a promising alternative for the traditional Haber-Bosch process. In this study, we present a method for improving the ENRR by controlling the wettability of the catalyst surface, suppressing the hydrogen evolution reaction (HER) while facilitating N2 adsorption. Reduced-graphene ox...

Due to the large Gibbs free energy of metal telluride for hydrogen generation, tellurium (Te) based materials are rarely reported as catalysts for overall water splitting. Herein, a facile hydrothermal method is used to engineer the stacked flower-like NiTe-NiSe nanosheets, thus nearing the application of transition metal telluride in clean and ren...

The "shuttle effect" of lithium polysulfides (LiPSs) leads to loss of active materials and the deterioration of cycle stability, which seriously restricts the practical progress of lithium-sulfur (Li-S) batteries. The diffusion of soluble discharge intermediate is the root cause of the above problems. Herein, we synthesized a porous organic framewo...

Interfacing an electrocatalyst with photoactive semiconductor surfaces is an emerging strategy to enhance the photocathode performance for the solar water reduction reaction. Herein, a core-shell heterostructure photocathode consisting of vanadium disulfide (VS2) as a 2D layered electrocatalyst directly deposited on silicon nanowire (Si NWs) surfac...

The development of robust, low-cost and efficient oxygen evolution reaction (OER) electrocatalysts, especially non-noble-metal-based OER catalysts, is of great significance and imperative to address the energy crisis, but remain challenging. Herein, a biomass-derived three-dimensional (3D) porous carbon/cobalt silicate (C/Co2SiO4) architecture is d...

For commercially viable direct methanol fuel cells, electrocatalysts play a crucial role in motivating the sluggish methanol oxidation reaction (MOR) over anode. Unfortunately, the large-scale applications of current MOR catalysts are hampered by their poor tolerance to poisoning and fast activity degradation. Herein, a unique composite catalyst co...
