Summary: A temperature gradient-driven mechanism is revealed for the evolution of hollow structure in hierarchical porous and hollow Co-CoO@NC spheres. The novel hierarchical Co-CoO@NC structure exhibits increased capacity by fully utilizing the interior active material and providing extra space for volume variation, resulting in a capacity of 919.3 mAh g-1 at 200 mA g-1 over 200 cycles. The reactivation of solid electrolyte interface (SEI) films and the introduction of nanosized Co particles contribute to the reversible capacity increase. This study provides a guide for constructing anodic materials with exceptional electrochemical performance.

Summary: This study presents an efficient direct Z-scheme heterostructure of ultrathin CsPbBr3/g-C3N4 nanosheets for photocatalytic reduction of CO2 to CH4 and CO with oxidation of H2O. In situ XPS analysis reveals a direct Z-scheme charge transfer mechanism at the CsPbBr3 and g-C3N4 interface, enabling efficient charge separation and high redox potentials for simultaneous CO2 reduction and H2O oxidation. Isotopic labelling experiments demonstrate that adsorbed water is activated to release H atoms and assist CO2 reduction. Theoretical calculations show the hybridization of Pb p orbitals with CO2, enhancing the affinity and weakening the binding strength. This work provides important insights and guidance for constructing high-efficiency catalysts for CO2 reduction with H2O oxidation.
