Materials supply and its proper utilization is needed for industries in electronics due to their rapid growth. These electronic industries produce many e‐wastes, which are a serious hazard to the environment. Electronic materials generally contain resin and silica. Even resin contains 80% of silica. A huge amount of silica present in e‐waste is wasted. So, this silica from e‐waste is used to prepare porous molecular sieves that contain NMs. Thus, recycling resin from e‐waste can be a sustainable approach for the environment [72]. Liou et al. synthesized mesoporous silica with high purity and larger surface from resin ash having a pore size of 3 nm. This approach can minimize the disposal problem of electronic items, which is again a benefit for sustainable environment [72].
