Effect of synthesized ZnO nanograins using a precipitation method for the enhanced cushion rubber properties

Optical, morphological and biological analysis of zinc oxide nanoparticles (ZnO NPs) using Papaver somniferum L.

“…The chemical procedures used for preparing nanosized ZnO NPs include solvothermal, sol-gel, sonochemical, electrodeposition, hydrothermal and spray pyrolysis. [10][11][12][13][14] However, synthesis by physical and chemical means has disadvantages. Physical methods require large amounts of energy and are timeconsuming while chemical methods produce noxious chemicals, which are unfriendly for the environment.…”

Facile Preparation of ZnO Nanoparticles and Ag/ZnO Nanocomposite and Their Photocatalytic Activities under Visible Light

“…In comparison to other oxide semiconductors, ZnO has many superior properties such as light sensitive, thermal and chemically stable, low cost, nontoxic, and sustainable with hydrogen environment [3]. The ZnO-based materials have many applications in industries, for example, rubbers, ceramics, pharmaceuticals, agricultural servants, paints, cosmetics, and photocatalysts [4][5][6][7][8][9][10]. Besides the advantages of this material due to the high electron aperture rate and low charge separation efficiency [11], the pure ZnO often exhibits relatively low photocatalytic activity under visible light irradiation, and therefore, ZnO does not meet the requirements of a photocatalyst when applied to practical processes [3,12,13].…”

Green synthesis of ZnO nanoparticles via Agathosma betulina natural extract

“…Generally, such processes require high vacuum and are energy consuming. While the chemical methods such as solvothermal, sol-gel, sonochemical, spray pyrolysis, hydrothermal, and electrodeposition processes [13][14][15][16][17] are cost effective and mass-production oriented, they are environmentally unfriendly. To mitigate the problem of energy unbalance and generated hazardous waste by the two major processes, greener approaches are being researched.…”
