“…The optimal reaction pathway could be revealed by calculating the Gibbs free energy (Δ G ) of the rate-determining step. By studying the transition state of the PS MPs degradation process, the generation path of the target product can be revealed . DFT calculations combined with in-situ experiments could comprehensively evaluate the reaction mechanism of photocatalytic MPs conversion.…”

Microplastics (MPs, particle size < 5 mm) have become increasingly ubiquitous on Earth due to the cleavage and degradation of the heavy use of plastics. MPs have recently been reported to be detected in human blood, alveoli, breast milk, embryos, and other organs, raising concerns about their environmental risks. Photocatalysis has been identified as a potential means for MPs conversion, which utilizes solar energy to stimulate a semiconductor photocatalyst. However, the study of photocatalytic conversion of MPs is still in the incubation period. This review overviews the current state-of-the-art technologies for MPs conversion. Then, the fundamental principles, challenges, analytical techniques, and evaluation indexes of photocatalytic MPs reforming are highlighted. We have systematically summarized the recent advances in the photocatalytic conversion of MPs and identified the key factors influencing photocatalytic performance. Finally, we propose some perspectives for developing efficient photocatalytic systems for reforming MPs. This review will provide a guideline for developing and applying photocatalytic technology for reforming MPs, which will significantly contribute to developing this emerging research field.

Development of advanced electrocatalysts for the green hydrogen production by water electrolysis is an important task to reduce the climate and environmental issues as well as to meet the future energy demands. Herein, Ru/Ni‐B‐P sphere electrocatalyst is demonstrated by a combination of hydrothermal and soaking approaches, meeting the industrial requirement of low cell voltage with stable high‐current operation. The Ru/Ni‐B‐P sphere catalyst demonstrates low overpotentials of 191 and 350 mV at 300 mA cm−2 with stable high current operation, ranking it as one of the best oxygen evolution reaction (OER) electrocatalysts. The bifunctional 2‐E system demonstrates a low cell voltage of 2.49 V at 2000 mA cm−2 in 6 m KOH at 60 °C of harsh industrial operation condition. It also demonstrates outstanding stability with continuous 120 h (5 days) CA operation at 1000 mA cm−2. Further, the hybrid configuration of Ru/Ni‐B‐P || Pt/C being paired with the conventional benchmark electrode demonstrates a record low 2‐E cell voltage of 2.40 V at 2000 mA cm−2 in 6 m KOH and excellent stability at high current of 1500 mA cm−2 under industrial operational condition.
