Ultrafast Room‐Temperature Synthesis of Large‐Scale, Low‐Cost, and Highly Active Ni─Fe Based Electrodes toward Industrialized Seawater Oxidation

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(39)

Published: Sept. 3, 2023

Abstract It is of significance to develop an active, efficient electrocatalyst for the oxygen evolution reaction (OER) as this determines efficiency and cost water/seawater electrolysis. Here, a cost‐effective Ni─Fe hydroxide promising OER catalyst developed by 1 min ultrafast method. The shows low overpotentials 240 254 mV at 10 mA cm −2 in both m KOH alkaline seawater, respectively. also exhibits excellent electrochemical stability. In situ Raman spectra other physical characterizations prove incorporation Fe transformation Ni(Fe)(OH) 2 Ni(Fe)OOH are responsible enhancement performance. Furthermore, can be readily scaled up synthesized within min. with size 2000 still remains electrochemically uniform. electrolysis cell integrated anode commercialized porous NiMo foam cathode has demonstrated current density 200 2.3 2.9 V 6 seawater 60 °C, Therefore, synthesized, earth‐abundant scalable, economical, highly active OER, which industrial splitting applications.

Technologies for the wastewater circular economy – A review

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100205 - 100205

Published: Jan. 1, 2024

Throughout the years, experiments with membrane, electrochemical, biological and thermal technologies have been explored to recover resources from a range of wastewaters such as municipal, industrial, urine sewage sludge. However, multiple resource recoveries at commercial pilot scale are still lacking, instead, focusing on specialising recovery narrow set products. Herein, divergence across municipal industrial wastewater streams – nutrients energy for municipal; heavy metals water streams; material seen both was observed through literature review. This review aims provide perspective academic professionals alike current available their emerging trends tie in these circular economics. Consequently, high sludge transportation costs may pressure treatment plants (WWTPs) adopt value-adding, onsite transforming centralised decentralised WWTPs into facilities.

Recent advances in wastewater microalgae-based biofuels production: A state-of-the-art review

Energy Reports, Journal Year: 2022, Volume and Issue: 8, P. 13253 - 13280

Published: Oct. 17, 2022

Rapidly expanding industrialization and the depletion of non-renewable fossil fuels have necessitated discovery feasible renewable alternatives to meet rising energy demand while reducing carbon dioxide (CO2) emissions. The present global strategy is built on cost-effective environmentally friendly alternatives; production microalgae has ability these requirements. Microalgae been found as a promising sustainable alternative for treating wastewater (WW) concurrently with biofuel production. One potential strategy, which uses lowering level contamination in WW called bioremediation. There are substantial gains be made both economy environment through integration microalgae-based treatment (WWT). use that short life span, high growth rate, CO2 usage efficiency one approaches producing biomass from nutrients involves utilization resources. most resources thermochemical conversion processes liquid gaseous biofuels due their advantages over other feedstocks, such sustainability, renewability, productivity. Currently, technology cost primary obstacles limiting industrial applicability, necessitates an optimum downstream process minimize costs. Consequently, concurrent WWT challenges practical economically viable. This review provides overview bioremediation bioenergy applications. It also insight future research investigate additional possible applications microalgal biomass. These could include not only process, but generation revenues incorporation clean green technology, would provide long-term sustainability environmental benefits.
