Summary: Three-dimensional palm frondlike S-scheme heterojunction based Co3O4@NiO/graphitic carbon composites were fabricated as photocatalysts for CO2 reduction reactions. The optimal Co@Ni/GC-700 catalyst exhibited excellent performance and stability with maximum yields of 9.79 µmol g-1h-1 for CH4 and 4.89 µmol g-1h-1 for CO under visible light irradiation. The superior photocatalytic CO2RR activity of the Co@Ni/GC catalysts can be attributed to the direct S-scheme heterojunction induced by the interfacial electric field (EF) and the improved CO2 adsorption capacity.

Summary: In this work, an ultrathin solid-state electrolyte (SSE) named LA-SSE was developed by combining a lipoic acid-assisted semi-interpenetrating polymer network and an ultrathin porous membrane. LA-SSE, with a thickness of only 10 μm, showed excellent mechanical properties to suppress lithium dendrite growth and favorable interfacial compatibility between the lithium anode and electrolyte.
