Self-standing Fe₃O₄ decorated paper electrode as a binder-free trifunctional electrode for electrochemical ammonia synthesis and Zn–O₂ batteries

Abstract

The conversion of the abundant biodegradable material into electro-active electrode material can be a good asset for sustainable energy conversion and storage applications. Herein, we present a simple, cost-effective and...

First‐Row Transition Metals for Catalyzing Oxygen Redox

“…Electroless deposition can further enhance the bifunctional activity via combining with other deposition approaches, such as electrodeposition, chemical vapor deposition, etc. For instance, Kafle et al [327] developed self-standing Fe 3 O 4 bifunctional electrocatalysts by coating an insulating cellulose paper into a biodegradable conductive substrate by electroless deposition, and then depositing Fe 3 O 4 nanospheres onto a nickel boride via an electrodeposition.…”

Self-powered NH3 synthesis by trifunctional Co2B-based high power density Zn–air batteries

“…[25][26][27][28] However, so far, only three reports are available wherein ZABs have been used to power electrochemical NH 3 synthesis. 12,29,30 Several classes of catalysts, including noblemetal-based, [31][32][33] non-noble metal-based 34,35 and metal freebased catalysts, [36][37][38] have been explored towards NRR in aqueous media, but the faradaic efficiency (F.E.) and NH 3 production yield rate obstruct their attempt to be put into practice.…”

Glucose oxidation assisted ammonia production via electrochemical dinitrogen reduction over CoWO4

“…However, their low abundance and high cost inhibit their wide-scale utilisation. 15 Thus, economic and earth-abundant transition metal-based electrocatalysts such as metal sulfides, 16,17 metal nitrides, 18,19 metal oxides, 20 etc. 21,22 have been reported.…”
