Recyclable catalyst of ZnO/SiO2 prepared from Salacca leaves ash for sustainable biodiesel conversion

This paper reports on the first case of the recyclable catalysts of ZnO/SiO2 prepared from salacca leaf ash as a source of silica for biodiesel production. The catalysts were prepared using a hydrothermal synthesis method, and the catalyst was utilized for biodiesel conversion from rice bran oil. Ph...
