after the reaction. The concentration of vanadium was found
to be 4.91% before the reaction and 4.88% after the 8th cycle
of the reaction. The SEM image of the catalyst after the 8th
cycle of the reaction did not show any change in the
morphology of the catalyst (ESI, Figure S2).The ICP-AES of
reaction solvent does not show traces of vanadium, thus
asserting that g-C3N4 holds the oxo-vanadium complex tightly,
which precludes vanadium leaching and promotes the
effective recycling of the catalyst.

Conclusions
A
simple and sustainable protocol for the oxidative
esterification of alcohol has been developed via photocatalytic
C-H activation using VO@g-C3N4 catalyst. The expeditious
reaction proceeds under neutral conditions due to the
photoactive graphitic carbon nitride surface and its strong
interaction with vanadium metal. The support stimulates the
metal towards the oxidation of alcohol followed by C-H
activation-esterification while the in-built nitrogenous
framework provides an adequate mild, basic environment and
energy through visible light absorption.
