Efficient reduction of nitrate to ammonia on AuPt@ZIF-8 composite film
Abstract
The nitrate reduction represents a sustainable strategy for water denitrification. Herein we design ZIF-8 coated porous AuPt alloy composite film for electrocatalytic nitrate reduction with superior ammonia yield of (131.5 ± 3.4) μg•h-1•mgcat-1, Faradaic efficiency of (95.8 ± 3.0) % and selectivity of 96%, overcoming individual Au, Pt, ZIF, and other widely-used Au-based alloy structure.
