Summary: Doping metal ions into cobalt sulfide is a promising strategy to enhance its electrocatalytic performance for overall water splitting. The synthesis of noble metal-free bifunctional electrocatalysts, composed of S, N, and O atoms co-incorporated porous carbon encapsulated Fe doped Co9S8 nanoparticles, is achieved by direct pyrolysis of S, Co, and Fe-based polypyrrole precursors. The optimal catalyst (Fe0-33-Co9S8@SNOPC) exhibits outstanding electrocatalytic activity in an alkaline electrolyte, with ultra-low overpotentials and exceptional stability for oxygen and hydrogen evolution reactions, as well as an extremely low cell voltage for overall water splitting.

Summary: The rise in CO2 concentration in the Earth's atmosphere is the main cause of environmental issues such as global warming and ocean acidification. Electrochemical CO2 reduction (CO2RR) is a promising green approach to convert CO2 into valuable products. Heteroatom-doped porous carbon-based (HA-PCs) catalysts are considered ideal for CO2RR due to their favorable properties and ability to meet sustainability and large-scale requirements. This review focuses on the rational synthesis of HA-PCs and the impact of dopants on CO2RR activity and durability. It also discusses the effects of CO2 on the environment and human health, recent advances in CO2RR pathways and mechanisms, and the challenges and future perspectives of HA-PCs for CO2RR.

Summary: Uniform, positively charged, and hollow mesoporous cubic silica particles (hmc-SiO2) prepared by a template approach were used to self-assemble into photonic crystals (PCs) with rhombohedral lattice. The reflection wavelengths and structural colors of the PCs can be controlled by altering the sizes or the shell thicknesses of the hmc-SiO2. Additionally, photoluminescent PCs were fabricated through click chemistry between amino silane and isothiocyanate of a commercial dye, providing potential applications in anticounterfeiting and information encryption.

The review also highlights the influence of material morphology and composition on the performance of MOF-derived CNMs in popular applications such as heterogeneous catalysis, fuel cells, and sensors.
