Developing an oxygen evolution reaction catalyst that exhibits both high catalytic activity and robust stability in acidic media remains a significant challenge to date. In this work, a RuZrOx/Ti-1 catalyst was successfully constructed on a Ti mesh substrate via a facile one-step pyrolysis method. Physical characterization reveals that the as-prepared RuZrOx/Ti-1 catalyst exhibits a densely packed nanosphere morphology on its surface, accompanied by abundant pores, which can provide a rich interface for the oxygen evolution reaction. The RuZrOx/Ti-1 catalyst achieves a low overpotential of only 199 mV for the OER at a current density of 10 mA·cm−2 and demonstrates excellent long-term durability, operating stably for 400 h at this current density. In summary, this work provides a viable strategy for designing high-performance acidic OER catalysts, thereby paving the way for the advancement of electrodes for water oxidation.
This review aims to address the environmental issues associated with the textile sector and explores innovative and optimal approaches for the zero-waste recycling of post-consumer cotton waste. The textile industry can transition toward a circular economy by implementing various recycling techniques. This will significantly cut the waste and raw material consumption, while promoting sustainability and environmental responsibility in textile manufacturing and consumption practices. This study focuses on several key techniques, including producing carbon fibres from waste, which provides a sustainable alternative to petroleum-based precursors. In addition, the regeneration of viscose fibres is achieved by chemical recycling of cotton waste and enzymatitc recycling. Method of Gasification and Thermochemical Valorisation, ioncell process is also discussed, emphasizing its potential to encourage resource conservation and lessen dependency on virgin resources. It also explains how cellulose nanofibrils (CNFs) can be extracted from post-consumer textiles and utilised to produce high-performance materials. Additionally, despite difficulties in preserving fibre quality, the potential of mechanical recycling techniques to yield viable yarns from recycled fibres is investigated.
