摘要
The rational preparation and development of efficient and stable non-precious metal catalysts for the hydrogen evolution reaction are an effective solution to solve the global energy shortage and the increasing environmental pollution problems. Herein, two Co-MOFs with similar structures were designed and synthesized, one based on sulfur-containing organic ligand and the other based on non-sulfur-containing organic ligand. The electrocatalytic performance results showed that the materials based on sulfur-containing organic ligand had a better electrocatalytic hydrogen evolution performance. The reasons of performance differentiation were analyzed by various characterization techniques.
