Frontispiz: Strong Circularly‐Polarized Room‐Temperature Phosphorescence from a Feasibly Separable Scaffold of Bidibenzo[<i>b</i>,<i>d</i>]furan with Locked Axial Chirality

Electrochemical CO2 reduction reaction (CO2RR) is an attractive pathway to convert CO2 into value‐added chemicals and fuels. Copper (Cu) is the most effective monometallic catalyst for converting CO2 into multi‐carbon products, but suffers from high overpotentials and poor selectivity. Therefore, it is essential to design efficient Cu‐based catalyst to improve the selectivity of specific products. Due to the combination of advantages of organic and inorganic composite materials, organic‐inorganic composites exhibit high catalytic performance towards CO2RR, and have been extensively studied. In this review, the research advances of various Cu‐based organic‐inorganic composite materials in CO2RR, i. e., organic molecular modified‐metal Cu composites, Cu‐based molecular catalyst/carbon carrier composites, Cu‐based metal organic framework (MOF) composites, and Cu‐based covalent organic framework (COF) composites are systematically summarized. Particularly, the synthesis strategies of Cu‐based composites, structure‐performance relationship, and catalytic mechanisms are discussed. Finally, the opportunities and challenges of Cu‐based organic‐inorganic composite materials in CO2RR are proposed.

Co nanoparticles embedded in P, N ‐dual doped porous carbon/rGO (P, N‐PCCo/rGO) were obtained through electrostatic interaction and high‐temperature pyrolysis with good electrical conductivity and ultrahigh specific surface area. At a current density of 10 mA cm−2, the overpotentials of P,N‐PCCo/rGO during acidic hydrogen evolution (HER) and alkaline oxygen evolution (OER) are 89 mV and 235 mV, respectively. The performance is significantly enhanced with increasing current density, even better than commercial Pt/C and IrO2 in electrocatalytic water splitting. Besides, P,N‐PCCo/rGO have a large half‐wave potential (∼0.872 V) and kinetic current Jk (11.76 mA cm−2) for oxygen evolution reaction (ORR). GO together with porous carbon constrains the growth of Co particles based on assisted synthesis. P, N co‐doped Co particles cause lattice defects of carbon, which form multiple active sites and provide more reaction channels for active species, thereby improving the HER, OER and ORR performance of the P,N‐PCCo/rGO trifunctional catalyst. GO‐assisted preparation of ultra‐thin porous P,N‐PCCo/rGO samples has laid a solid foundation for designing and implementing a series of multifunctional catalysts for graphene oxide‐based heteroatoms (N, P, S, etc.) doped with non‐noble metal embedded porous carbon.
