The reduction–oxidation treatment can reconstruct Pd nanoparticles, strengthen metal–support interactions and enhance catalytic performance of Pd/H-ZSM-5 in methane combustion.
Nickeltitanate (Ilmenite) has been prepared with stoichiometric variation by substituting Mn in the ‘A’ site, using the sol–gel method in a highly active form.
Sponge-like carbon-supported nickel nitride is prepared using a facile sol–gel method and is shown to be highly active for electrocatalytic water oxidation.
Novel Cu–Ce–Zr mixed oxides were synthesized by a citric acid sol–gel method, and they exhibited an excellent NH3-SCO activity (180 °C, TOF = 1.33 h−1).
