Stabilizing the interfacial Cu0-Cu+ dual sites toward furfural hydrodeoxygenation to 2-methylfuran via fabricating nest-like copper phyllosilicate precursor

•Nest-like copper phyllosilicate (CuSi-N) precursor was fabricated through P123-assisted hydrothermal crystallization.•The reduced CuSi-N exhibits excellent catalytic performance toward gas hydrodeoxidation of furfural to 2-methylfuran.•Cu+ serves as the adsorption center of CO bond in furfural and CO bond in furfuryl alcohol intermediate.•The synergistic catalysis of Cu0-Cu+ dual sites plays a vital role in determining the catalytic behavior.
