Application


  • Enhanced adsorption-catalysis for sulfur removal: Describes the use of trimethoxymethylsilane for improving adsorptive and catalytic properties in fuels processing (J Ortiz-Bustos, HP Del Pulgar, Y Perez, 2023).

  • Preparation of organic-inorganic hybrid materials: Discusses the hybridization of materials using titanium phosphonate clusters combined with silanes for enhanced material properties (R Hayami, K Wada, I Nishikawa, T Sagawa, 2017).

  • Development of a molecularly imprinted polymer sensor: Utilizes trimethoxymethylsilane in the creation of a polymer sensor for detecting specific substances, highlighting its application in sensing technologies (K Wang, X Guan, S Chai, Q Zou, X Zhang, 2015).

  • Anti-fingerprint properties on glass surfaces: Explores the application of trimethoxymethylsilane in creating non-fluorinated organosiloxane coatings with anti-fingerprint properties (A Siriviriyanun, T Imae, 2014).
