Electroreforming injects a new life into solid waste

Abstract

This review draws the similarities between electroreforming of biomass and plastic derivatives and highlights the pretreatment of raw solid waste, the innovation in catalyst design, and mechanism investigation of waste derivative conversion.

Green and alcohol-free H2O2 generation paired with simultaneous contaminant treatment enabled by sulfur/cyano-modified g-C3N4 with efficient oxygen activation and proton adsorption

“…1–5 However, the current anthraquinone (AQ) method for the industrial production of H 2 O 2 in large scale still faces some disadvantages, like the consumption of energy and unavoidable environmental pollution caused by toxic by-products. 6–9 The photocatalytic reduction of oxygen for H 2 O 2 generation seems to be an energy-saving and sustainable strategy when considering synchronous solar-to-chemical conversion and environmental protection. 10,11 Nevertheless, the trade-off between high yields and unavoidable costs over excessive usage of alcohols as sacrificial agents and low reaction activity in pure water still makes this process not green enough.…”

Beyond biodegradation: upcycling of polylactic acid plastic waste into amino acids via cascade catalysis under mild conditions

“…16–18 Moreover, such a natural degradation process enables a carbon footprint and a waste of carbon resource present in PLA plastic. 19,20 Additionally, the degradation rate of PLA plastic relies heavily on the environments in which it ends up, such as soil and seawater (PLA plastic is basically non-degradable in seawater). 21–23 These challenges have incentivized the development of chemical recycling technologies that allow for the recovery of the monomer constituents ( i.e.…”

Sulfur-regulated metal–support interaction boosting the hydrogen evolution performance of Ru clusters in seawater at industrial current densities

“…Using earth-abundant seawater as the feedstock is crucial to decrease the cost of water splitting. [28][29][30] Unfortunately, due to the complex environments of seawater, it is still a great challenge to develop highly active and durable HER catalysts which can work in real seawater at industrial scale current densities.…”
