Dangling Bonds (DBs) on the silicon surface exist when a silicon atom lacks a bonding partner, resulting in a localized orbital which is not involved in any chemical bonds. On the hydrogen-terminated Si(100) surface, such DBs introduce a mid-gap state. DBs can be created on this surface by the...

Solution processed Hafnia nanoaggregates: influence of surface oxygen on catalytic soot oxidation
Download2022-09-26
Hafnium dioxide (HfO2) nanoaggregates are synthesized by sol–gel and hydrothermal routes followed by hydrogen annealing at different time durations. The proposed study aims to explore the effect of hydrogen annealing time on the properties of HfO2 and also envisage the catalytic soot oxidation...

Surface fluorination of α-Fe2O3 using selectfluor for enhancement in photoelectrochemical properties
Download2022-09-22
Fluorinated α-Fe2O3 nanostructures are synthesized via a facile hydrothermal route using Selectfluor™ (F-TEDA) as a fluorinating as well as growth directing agent. The addition of incrementally increasing amount of F-TEDA to Fe precursor under hydrothermal conditions resulted in preferential...

Water-splitting photoelectrodes consisting of heterojunctions of carbon nitride with a p-type low bandgap double perovskite oxide
Download2022-09-25
Quinary and senary non-stoichiometric double perovskites such as Ba2Ca0.66Nb1.34−xFexO6−δ (BCNF) have been utilized for gas sensing, solid oxide fuel cells and thermochemical CO2 reduction. Herein, we examined their potential as narrow bandgap semiconductors for use in solar energy harvesting. A...
