“…A composite consisting of CeO 2 /Ce 2 O 3 /NiO x with an average crystal size of 22.4 nm was obtained by increasing microwave power to 700 W. When microwave power is increased to 900 W (d3), however, CeO 2 nanoparticles with an average crystal size of 4.9 nm are almost formed. Our previous research indicated that microwave pulses are an important parameter affecting the crystallinity and morphology of the final product 31 – 33 . The synthesis of catalysts was carried out under three different pulse conditions (30 s on, 60 s off, and 30 s on, 30 s off).…”

In order to advance desulfurization technology, a new method for excellent oxidative desulfurization of fuel at room temperature will be of paramount importance. As a novel desulfurization method, we developed piezo-catalysts that do not require adding any oxidants and can be performed at room temperature. A microwave method was used to prepare CeO2/Ce2O3/NiOx nanocomposites. Model and real fuel desulfurization rates were examined as a function of synthesis parameters, such as microwave power and time, and operation conditions, such as pH and ultrasonic power. The results showed that CeO2/Ce2O3/NiOx nanocomposites demonstrated outstanding piezo-desulfurization at room temperature for both model and real fuels. Furthermore, CeO2/Ce2O3/NiOx nanocomposites exhibited remarkable reusability, maintaining 79% of their piezo-catalytic activity even after 17 repetitions for desulfurization of real fuel. An investigation of the mechanism of sulfur oxidation revealed that superoxide radicals and holes played a major role. Additionally, the kinetic study revealed that sulfur removal by piezo-catalyst follows a second-order reaction kinetic model.

“…2) As the energy harvesting system, the integration of the smart ZIB with the photo-rechargeable system (solar battery) or the friction power generation system (triboelectric nanogenerator) could realize the reversible energy storage and conversion. [198,199] The effective integration could significantly reduce the inner volume space and the weight of the wearable electronics, which is also beneficial for the utilization and portability. [197] It is also the direct strategy to achieve the collection of discontinuous resources, and provide the continuous energy supplying in the integrated system for electronic devices in future.…”

Natural sources of green energy include sunshine, water, biomass, geothermal heat, and wind. These energies are alternate forms of electrical energy that do not rely on fossil fuels. Green energy is environmentally benign, as it avoids the generation of greenhouse gases and pollutants. Various systems and equipment have been utilized to gather natural energy. However, most technologies need a huge amount of infrastructure and expensive equipment in order to power electronic gadgets, smart sensors, and wearable devices. Nanogenerators have recently emerged as an alternative technique for collecting energy from both natural and artificial sources, with significant benefits such as light weight, low-cost production, simple operation, easy signal processing, and low-cost materials. These nanogenerators might power electronic components and wearable devices used in a variety of applications such as telecommunications, the medical sector, the military and automotive industries, and internet of things (IoT) devices. We describe new research on the performance of nanogenerators employing several green energy acquisition processes such as piezoelectric, electromagnetic, thermoelectric, and triboelectric. Furthermore, the materials, applications, challenges, and future prospects of several nanogenerators are discussed.
