Developing efficient and robust metal-nitrogen-carbon electrocatalysts for oxygen reduction reaction (ORR) is of great significance the application hydrogen-oxygen fuel cells metal-air batteries. Herein, a coordination engineering strategy developed to improve ORR kinetics stability cobalt-nitrogen-carbon (Co-N-C) by grafting oxygen-rich graphene quantum dots (GQDs) onto zeolite imidazole frameworks (ZIFs) precursors. The optimized GQDs-functionalized Co-N-C (G-CoNOC) electrocatalyst...
Exploring low-cost, efficient, and stable nonprecious alternatives for Pt-based catalysts is of significance in the hydrogen evolution reaction (HER) acidic environments. Previous experiments have found that 3d transition metals Fe, Co, Ni incorporated with inert carbon templates or carbon–nitrogen materials exhibit long-term durability high HER activity electrolytes. To clarify underlying mechanism determining activity, here we report a theoretical investigation on series defective...
Rationally designed structures and elements are important for the construction of effective electrocatalysts water splitting. Herein, we developed an ultrathin hierarchical P-doped MoS2/Ni3S2 heterostructure on nickel foam (NF) by a one-pot synthesis.

The catalytic activities of single-atom catalysts (SACs) are strongly influenced by the local chemical environments their substrates, which electronic structures SACs can be effectively tuned. Together with freedom available reactive metallic centers, it would feasible to maximize performance means a synergetic optimization in space spanned features both substrate and center. In this work, using first-principles calculations, we systematically assessed effect between geometric/electronic...
Efficient catalysts for the electroreduction of N2 to NH3 are paramount importance sustainable ammonia production. Recently, it was reported that NbSe2 nanosheets exhibit an excellent catalytic activity nitrogen reduction under ambient conditions. However, existing theoretical calculations suggested overpotential over 3.0 V, which is too high interpret experimental observations. To reveal underlying mechanism activity, in this work, we assessed edges with different chirality and Se vacancies...
Abstract Developing highly efficient photocatalysts for converting CO2 into solar fuels is of great importance energy sustainability. However, photoreduction over the heterogeneous catalyst hindered by lack precisely controlled active sites and poor contact between semiconductor, which leads to low selectivity photochemical stability catalyst. Herein, utilizing stable readily tunable photoresponsive covalent triazine frameworks (CTFs) as intriguing platforms, well-defined molecular catalysts...
Abstract Strain engineering has been widely used in the study of two‐dimensional semiconductors recent years, because it can improve catalytic performance by changing structural characteristics materials.
