Polymer Nanocomposite Hydrogels for Water Purification

Hydrogen evolution from water splitting on nanocomposite photocatalysts

The photocatalytic production of H2 in one step is potentially one of the most promising ways for the conversion and storage of solar energy. The paper overviews our recent studies on the photocatalysts splitting water into hydrogen under irradiation. The attention was mainly focused on the promotion effects of nanosized modifications in the interlayer and surface of photocatalysts for hydrogen...

Nanocomposite heterojunctions as sunlight-driven photocatalysts for hydrogen production from water splitting.

Hydrogen production via photocatalytic water splitting using sunlight has enormous potential in solving the worldwide energy and environmental crisis. The key challenge in this process is to develop efficient photocatalysts which must satisfy several criteria such as high chemical and photochemical stability, effective charge separation and strong sunlight absorption. The combination of differe...

Utility of adsorbents in the purification of drinking water: a review of characterization, efficiency and safety evaluation of various adsorbents.

Clean drinking water is one of the implicit requisites fora healthy human population. However the growing industrialization and extensive use of chemicals for various concerns, has increased the burden of unwanted pollutants in the drinking water of developing countries like India. The entry of potentially hazardous substances into the biota has been magnifying day by day. In the absence of a p...

Novel chitosan-cellulose hydrogel adsorbents for lead adsorption

In this study, we examined the properties of chitosan-cellulose hydrogel beads as an adsorbent and its application for lead ion adsorption. Chitosan was blended with cellulose to improve the mechanical strength of chitosan hydrogel beads and the chitosan-cellulose hydrogel beads were cross-linked with ethylene glycol diglycidyl ether (EGDE) to enhance their acid-resistant ability. Scanning elec...
