Hydrothermal Approach

A POM@rGO monolith reactor was constructed using a facile and broad-spectrum hydrothermal approach and it effectively catalyzes epoxide ring-opening reactions with 99% conversion and over 90% selectivity, reaching a turnover number (TON) of around 28 044 after 38 h catalysis.
