Several application fields can benefit from solar-hydrogen technologies <italic>via</italic> specific short-term and long-term pathways.
Separation of electrolysis products using fluidic inertial forces in a 3D printed flow cell.
Affordable, stable and earth-abundant photo-electrochemical materials are indispensable for the large-scale implementation of sunlight-driven hydrogen production. Here we present an intrinsically scalable solar water splitting device that is fully based on materials, with a solar-to-hydrogen conversion efficiency 14.2%. This unprecedented achieved by integrating module three interconnected silicon heterojunction cells operates at appropriate voltage to directly power microstructured Ni...
Abstract Chlorine is a large‐scale chemical commodity produced via the chloralkali process, which involves electrolysis of brine in membrane‐based electrochemical reactor. The reaction normally driven by grid electricity; nevertheless, required combination voltage–current can be guaranteed using renewable power (i.e., photovoltaic electricity). This study demonstrates an off‐grid solar‐powered chlorine generator that couples novel planar solar concentrator, multijunction InGaP/GaAs/InGaAsNSb...
Sodium hypochlorite (NaClO) is a chemical commodity widely employed as disinfection agent in water treatment applications. Its production commonly follows electrochemical routes an undivided reactor. Powering the process with photovoltaic (PV) electricity holds potential to install stand-alone, independent generators and reduce NaClO cost. This study reports comparative assessment of autonomous, solar-powered sodium employing different technologies: silicon hetero-junction (SHJ)...
On-site generation of sodium hypochlorite (NaClO) holds the potential to bring an efficient and cost-effective water disinfection method isolated remote locations. Solar-driven, stand-alone reactors could provide those communities full independence by ensuring continuous treatment drinking water. In this study we build compare performance two different classes electrolyzers for generation: first one is flow-based, mimicking commercially employed at large scale; second class batch-type,...
The implementation of practical solar-fuel technologies can trigger a significant increase in the use renewables our energy ecosystem. These directly capture and store solar form rich molecules, which could be used at later stage as fuels for transportation or electricity generation. Storing solar-energy into also serve mean seasonal storage, so that excess summer during periods low irradiation winter. Also, generators operated centralized facilities without disrupting operation grid....
We successfully demonstrated and reported the highest solar-to-hydrogen efficiency with crystalline silicon cells Earth-abundant electrocatalysts under unconcentrated solar radiation. The combination of hetero-junction a 3D printed Platinum/Iridium-Oxide electrolyzer has been proven to work continuously for more than 24 hours in neutral environment, stable 13.5% solar-to-fuel efficiency. Since hydrogen economy is expected expand global scale, we same an based on Nickel basic medium. In both...
Over one billion people currently lack access to safe potable water. Those communities, often isolated or settled in remote locations, are thus constantly exposed a severe health threat due waterborne pathogens (e.g. cholera, typhus, etc.). It is therefore evident that unavailability of drinking water directly hampers hygiene, education and ultimately societal development. Chemical treatments commonly employed remove organic contaminants from The injection certain dose chlorine chlorinated...
Chlorine is a chemical commodity widely used; it estimated to be employed in half of the goods used and consumed on daily basis. One main sector water treatment, where chlorine other chlorinated compounds are as powerful disinfectant agents remove waterborne pathogens from reservoirs or effluents. most commonly produced via electrochemical routes (the so-called chlor-alkali process), membrane-based reactor. Concentrated sodium chloride brines (20-26% weight) utilized anolytes; ions undergo...
