Abstract:This study reports a sustainable approach for developing electrodes for microsupercapacitors. This approach includes the synthesis of TiO2 nanoparticles via a green sol–gel method and the deposition of thin films of that electrochemically active material on three-dimensional (3D) Si substrates with a high area enlargement factor (AEF) via a simple, fast, and inexpensive spin-coating pathway. The thickness of the film was first optimized via its deposition over two-dimensional (2D) substrates to achieve high ca… Show more
