Coordination Structure Modulation in Group-VIB Metal Doped AgPO Augments Active Site Density for Electrocatalytic Conversion of N to NH.

Doping is considered a promising material engineering strategy in electrochemical nitrogen reduction reaction (NRR), provided the role of the active site is rightly identified. This work concerns the doping of group VIB metal in AgPO to enhance the active site density, accompanied by d-p orbital mixing at the active site/N interface. Doping induces compressive strain in the AgPO lattice and inherently accompanies vacancy generation, the latter is quantified with positron annihilation lifetime studies (PALS).

Seasonal impact on microbiological quality of drinking water in Solan City of Himachal Pradesh, India.

Water contamination with faecal matter is usually the main cause of microbial waterborne diseases. Such diseases are an alarming situation for small cities in developing countries like India. In this research, to check the microbiological status of drinking water in Solan, Himachal Pradesh (India), water samples were collected from baories/stepwells (n = 14), handpumps (n = 9), and the municipal water distribution system (MWDS) (n = 2) in alternative months of the year (covering three main seasons).

Nanosheets of InS/S-CN-Dots for Solar Water-Splitting in Saline Water.

Hydrogen generation from splitting of water under the photoelectrochemical (PEC) pathway is considered as the most promising strategy for covering the upcoming fuel crisis by taking care of all environmental issues. In this context, InS can be explored as it is a visible light-active semiconductor with an appropriate band alignment with the water redox potential. Herein, InS nanosheets are developed by the chemical method.

Doping of MoS by "Cu" and "V": An Efficient Strategy for the Enhancement of Hydrogen Evolution Activity.

To replace Pt-based compounds in the electrocatalytic hydrogen evolution reaction (HER), MoS has already been established as an efficient catalyst. The electrocatalytic activity of MoS is further improved by tuning the morphology and the electronic structure through doping, which helps the band energy position to be modified. Presently, thin sheets of MoS (MoS-TSs) are synthesized via a microwave technique.

Aggregates of Ni/Ni(OH)/NiOOH Nanoworms on Carbon Cloth for Electrocatalytic Hydrogen Evolution.

The development of an efficient electrocatalyst for hydrogen evolution reaction (HER) is essential to facilitate the practical application of water splitting. Here, we aim to develop an electrocatalyst, Ni/Ni(OH)/NiOOH, electrodeposition technique on carbon cloth, which shows efficient activity and durability for HER in an alkaline medium. Phase purity and morphology of the electrodeposited catalyst are determined using powder X-ray diffraction and electron microscopic techniques.

Type-II Heterostructure of ZnO and Carbon Dots Demonstrates Enhanced Photoanodic Performance in Photoelectrochemical Water Splitting.

Hydrogen evolution through ecofriendly photoelectrochemical (PEC) water splitting is considered to be one of the most cost-effective and desirable methods for meeting ever-growing energy demands. However, the low photoconversion efficiency limits the practical applicability of PEC water splitting. To develop an efficient photoelectrode, here the morphology of ZnO is tuned from 0D to 3D.
