1. A process for the conversion of carbon dioxide to methanol, wherein the said process comprises steps of:
a) capturing/feeding carbon dioxide from a natural source or a chemical source;
b) treating the captured carbon dioxide with a self-folding property film present on an outer ceramic layer in presence of moisture, wherein said film comprises carbon derived from bamboo, alginate, and nanocellulose to obtain carbonic acid;
c) filtering the carbonic acid by a membrane filter to obtain filtered carbonic acid in an inner electrochemical cell;
d) hydrolysing the filtered carbonic acid to obtain carbon dioxide and water;
e) reducing, via electrochemical reduction, the obtained carbon dioxide in presence of an imprinted polymer with a selective 3D imprinted memory to obtain methanol,
wherein the reduction is carried out in the inner electrochemical cell containing an anode comprising zinc (Zn) quantum material; a cathode comprising nano quartz coated with nanozyme(s) incorporated the imprinted polymer with the selective 3D imprinted memory for the obtained carbon dioxide, and an electrolyte containing ethylene glycol and sodium hydroxide.
