Here we galvanically replace liquid galinstan with Pt to create PtGa nanoparticles <italic>via</italic> expulsion from the metal surface. These nanomaterials are active for a variety of electrocatalytic reactions.
Abstract A carbon dioxide capture, conversion, and utilization technology has been developed that can be powered by renewable energy with the potential to mitigate CO 2 emissions. This relies on an electrochemical process whereby dissolution of into carbonate ions is accelerated a locally induced pH change at cathode. The then complex metal cations, such as Ca 2+ , Sr or Mn present in solution form their respective carbonates, which precipitate out solution. To ensure cathode not fouled...
Galvanic replacement of liquid metal Galinstan under mechanical agitation with copper creates a multi-elemental system that is photocatalytically active for the degradation organic dyes where reuseability achieved via immobilisation on solid support.
Room temperature liquid metals based on gallium can be used as a sonochemical catalyst to degrade organic azo dyes into harmless carbon particles with different sizes. The metal is recoverable after each cycle and therefore reuseable.
Abstract Carbon dioxide is a greenhouse gas that contributes to global warming but fortunately can be removed via chemical conversion processes often involve reduction step. Dielectric barrier discharge (DBD) plasma an effective way promote requires catalyst for energetically demanding reactions. In this study, the rapid of CO 2 into solid carbon DBD reported using dispersed liquid metal Ga which first converted GaOOH particles ultimately form GaOOH/C nanocomposite. Raman and X‐ray...
Carbon capture and storage (CCS) is amongst the possible options to reduce CO2 emission. In application of CCS, techniques such as adsorption membrane system have been proposed due less energy requirement environmental benign than absorption process. However, has drawbacks poor reproducibility, scale-up difficulty high cost supports. this study synthesis characterization nanocomposite sodalite (HS)/ceramic via "pore-plugging" hydrothermal (PPH) protocol for pre-combustion reported. The...
Carbon dioxide emission is a major cause of environmental concern, such as global warming and ocean acidification. Therefore, there an ongoing search for feasible carbon reduction processes that utilize renewable energy to convert CO2 into valuable product. Here, we report versatile sonochemical process the permanent removal conversion acetamide liquid oxygenates using Ga metal-based reductant. Liquid metals are ideal due their notable catalytic properties at low temperatures, nontoxicity,...
Abstract The effective degradation of synthetic dyes via photocatalysis using abundant cheap materials is an ongoing challenge. Often photocatalysts are costly and employ complex fabrication processes that give limited efficiency which therefore inhibits widespread industrial proliferation. To address this issue, a simple room temperature alloying process followed by sonication for the preparation photocatalytically active GaZnO nanosheets confined on metallic GaZn core reported. material...
Anthropogenic carbon dioxide (CO 2 ), resulting from the world’s persistent reliance on fossil fuels as principal source of energy, has perturbed and induced an imbalance in natural carbon-cycle. This increased CO emission into environment been implicated global warming other environmental issues 1 . Therefore, coupling a sustainable energy system with reduction to produce valuable chemical compounds is being thoroughly investigated Among techniques developed for selective conversion,...
