system. Benefiting from their maneuverability and adjustability, the hydrothermal
and solvothermal method boosts the development of synthetic chemistry and attracts
much attention in the preparation of nanostructured catalysts, achieving a variety of
highly efficient catalysts [11, 19, 21, 30–36].
In the preparation of supported catalysts by hydrothermal/solvothermal method,
the detailed experimental process usually includes: dissolution of precursors, mixing
of solution, transferring the mixed solution to containers, sealing the containers by
stainless steel, putting the devices into heater (such as oven, tube furnace, heating
mantle, oil bath, microwave oven, etc.), and adjusting the heating–cooling reaction
parameters. Finally, the as-synthesized products are precipitated, washed, dispersed
on carbon supports and appropriately treated before obtaining the supported catalysts
[37, 38].
