| 초록 | Metal-organic frameworks (MOFs) provide an ideal platform for designing promising catalysts due to their porosity and diversity. However, most MOF materials are powders, which seem facile and straightforward, but are actually not optimal for practical application. To optimize the performance of MOF toward energy conversion applications, MOF-based catalyst can be grown on substrate, which is then used directly as an electrode. Herein, we report a procedure for direct growth of ZIF-67 on Co(OH)2/carbon paper (denoted as ZIF-67@Co(OH) 2 /CP). Then, the obtained ZIF-67@Co(OH)2/CP was etched by thioacetamide to achieve the final material CoxSy@Co(OH)2/CP (denoted as CS@CH/CP). The prepared catalyst showed remarkable OER activity with overpotential of 180 mV at 10 mA cm -2 , the Tafel slope of 96 mV dec -1, and negligible activity lost after 24h of continuous operating. |
