Introduction of A-site deficiency on Ni-doped LaSrCrO ₃ anodes helps form highly mobile oxygen vacancies and remarkably enhances Ni nanoparticle reducibility, and significantly increases electronic conductivity and catalytic activity.

A novel hydrothermal-conjugate-copolymerization strategy has been developed for the preparation of a carbon-rich g-C ₃ N ₄ photocatalyst.

Ni, Fe-doped A-site-deficient LaSrCrO₃were fabricated with anin situexsolution of uniformly dispersed nano Ni, Fe and Ni–Fe alloy, which enhance the electrical conductivity greatly and promote the electrochemical performance with better coking resistance.

Novel sponge-like ammonium-based PILs with rich exposed anion, excellent textural properties, and CO₂ adsorption were prepared for efficient CO₂ cycloaddition.
