| Abstract: | Exploring earth-abundant electrocatalyst with active and stable hydrogen evolution reaction (HER) properties is desirable but still challengeable. Herein, WP2 nanosheets are seamlessly grown on W foil (WP2 NSs/W) through phosphorization of WO3/W. This seamless WP2/W structure is beneficial to reducing the resistance between WP2 and W. Along with the exposed large density of active sites, WP2 NSs/W displays outstanding HER activity with a lower onset potential of about 0 V, a smaller overpotential of 90 mV for the current density of 10 mA/cm2 in basic media. Notably, WP2 NSs/W electrode also catalyzes HER efficiently in acid. The synthesis of WP2 NSs/W provides us a straightforward strategy to gain more cost-effective cathode for HER. |
