One-step CVD synthesis of carbon framework wrapped Co2P as a flexible electrocatalyst for efficient hydrogen evolution

Here, we develop a novel method to successfully prepare a nanohybrid catalyst of carbon framework wrapped cobalt phosphide on carbon cloth (Co2P[at]C/CC) as a flexible electrocatalyst for the HER. Relative to reported phosphides phosphatized using hypophosphite, the resulting Co2P[at]C/CC was prepar...

Description
Summary:Here, we develop a novel method to successfully prepare a nanohybrid catalyst of carbon framework wrapped cobalt phosphide on carbon cloth (Co2P[at]C/CC) as a flexible electrocatalyst for the HER. Relative to reported phosphides phosphatized using hypophosphite, the resulting Co2P[at]C/CC was prepared using a Co3(PO4)2 precursor via one-step chemical vapor deposition (CVD) reduction, thus obtaining highly purified Co2P. This moderate method paves a versatile path to designing earth-abundant alternatives for the HER.
