  • Conducting polymer and carbon nitride based nanocomposite photocatalyst for degradation of aqueous organic pollutants
    Patent number: 11819833
    Abstract: A nanocomposite photocatalyst is provided. The nanocomposite photocatalyst contains carbon nitride particles, a polymer composite comprising a conducting polymer and a carbon nanomaterial, the polymer composite being disposed on the carbon nitride particles, and noble metal nanoparticles disposed on both the polymer composite and the carbon nitride particles. Also provided is a method of forming the nanocomposite photocatalyst and a method of photodegrading an organic pollutant in water using the nanocomposite photocatalyst and visible light irradiation.

  • Surface modified electrodes and methods of preparation thereof
    Patent number: 11340187
    Abstract: A surface modified electrode, and methods for preparing the surface modified electrode for use in an electrochemical sensor for detection of an analyte is described. The surface modified electrode includes a copper oxide (CuO) co-doped tin dioxide (SnO2) nano-spikes disposed over a gold-plated chip. The surface modified electrode further includes a polymer matrix (nafion) configured to bind the gold-plated chip with the copper oxide (CuO) co-doped tin dioxide (SnO2) nano-spikes. The present disclosure also relates to a process of preparing the surface modified electrode. The surface modified electrode of the present disclosure can be used in electrochemical sensors for detection of analytes, like 4-nitrophenol (4-NP).
