Abstract

There have been reviews on the synthesis, characterization, modification, and application of TiO2 over the past 10 years in about 30,000 journals from the Sciencedirect.com website as a data source investigating capping agents and sensitizers from natural materials. The process of searching for data sources was continued with a filtering process according to several key words, namely "capping agent, sensitizer, natural, green, plant, extract"then obtained 25 selected articles that specifically reviewed the potential of plant extracts as capping agents and sensitizers in the synthesis of titanium oxide. The results of the review concluded that the shape and size of titanium oxide using a capping agent in the form of plant extracts such as starch, temulawak, soybean, aloe vera, curry tea, hibiscus rosa sinensis is spherical in shape with a size range of 7-160 nm and an average particle size of up to 30 -50 nm. Natural pigments and dyes such as anthocyanins and chlorophyll have been used as sensitizers in the last ten years. This review shows that the use of biomass as a source of capping agent and sensitizer increases efficiency because of the band gap and surface area. The plant extracts will provide several levels of efficiency in producing titanium oxide with various morphological variations and applications with band gap control.
