WSNs having radially oriented mesochannels were synthesized by a solvothermal method.
Pore structures of WSNs were varied using different molar ratios of CTAB to PVP.
WSNs were applied as carriers to immobilize CRL.
Esterification of oleic acid with methanol was catalyzed by WSNs-CRL.
WSNs-CRL were used as an efficient biocatalyst in the synthesis of biodiesel.
