Abstract

A novel ultrathin cobalt-based zeolitic imidazolate framework hybrid nanosheet array exhibits enhanced electrocatalytic activity for the oxygen evolution reaction.

Ultrathin tin monosulfide nanosheets with the exposed (001) plane for efficient electrocatalytic conversion of CO2 into formate

“…Inspired by the excellent CO 2 RR activity, a two-electrode electrolyzer was further assembled with the ultrathin SnS NS cathode for the CO 2 RR and an Ir/C anode for the oxygen evolution reaction (OER). [45][46][47][48][49][50][51][52] As shown in Fig. S12a, † the polarization curve of the CO 2 RR-OER cell displayed electrocatalytic properties, in which the current density could reach 6.54 mA cm À2 at 3.0 V. Notably, the current density was slightly decreased by only 10% aer 10 hours of continuous reaction (inset of Fig.…”

Carbon‐Rich Nonprecious Metal Single Atom Electrocatalysts for CO2 Reduction and Hydrogen Evolution

“…Compared with the deeply investigated OER, the HER is an inseparable, often overlooked component of water splitting, which has been widely considered to be a sustainable alternative to traditional fossil fuels . The two‐electron pathway of HER process is usually divided into two theoretical mechanisms in acid solution…”

Two-dimensional metal–organic frameworks and their derivatives for electrochemical energy storage and electrocatalysis

“…202 In addition, ZIF-67 can also be converted to 2D carbon-based materials for the ORR due to its transformation into a special 2D form during the heat treatment. 60,183,[203][204][205] For instance, graphene-like N,Co-CNSs derived from the ZIF-67 polyhedra via the molten salt method exhibited comparable catalytic performance toward the ORR as the ZIF-L derived materials. Furthermore, Huang and coworkers reported a facile method to fabricate a 2D Co-N codoped carbon based electrocatalyst (Co,N-CNS) by directly carbonizing the NaCl-caged 2D Co-MIM MOFs.…”
