Biodiesel production from expired cooking oil? Sponge-like catalysts pave the way for easy access
Multiple chemical reactions take place sequentially in the catalyst: the substrate molecules pass through the large pores of a “porous ceramic sponge” for the first reaction, and then enter the slightly smaller pores for the second reaction. The journal Nature Catalysis reported on October 26 that researchers from the Royal Melbourne Institute of Technology (RMIT)...
