摘要：Large-scale preparation of ultrathin 2D Co-based nanosheets is of great importance in the fields of catalysis, energy conversion, etc. Herein, we have developed a simple preparation method of 2D ultrathin alpha-Co(OH)(2) nanosheets by mixing an aqueous solution of Co salt and a methanolic solution of 2-methylimidazole at room temperature. The resulting alpha-Co(OH)(2) materials are nanosheets with an average thickness of similar to 2.5 nm and the size in micrometers. Benefiting from the ultrathi ...More
Large-scale preparation of ultrathin 2D Co-based nanosheets is of great importance in the fields of catalysis, energy conversion, etc. Herein, we have developed a simple preparation method of 2D ultrathin alpha-Co(OH)(2) nanosheets by mixing an aqueous solution of Co salt and a methanolic solution of 2-methylimidazole at room temperature. The resulting alpha-Co(OH)(2) materials are nanosheets with an average thickness of similar to 2.5 nm and the size in micrometers. Benefiting from the ultrathin thickness, this alpha-Co(OH)(2) nanosheet exhibits excellent oxygen evolution reaction performance with an overpotential of 267 mV at j = 10 mA cm(-2). This strategy can be applied to prepare other 2D Co-based layered double or triple hydroxides. Therefore, this work provides new strategies to prepare a series of 2D hydroxide nanosheets with solvent engineering and coordination competition. ...Hide
