DOI:
https://doi.org/10.3365/KJMM.2024.62.12.963
Abstract
Hydrogen sulfide (H
2
S) is a highly toxic and dangerous gas with a flammable and corrosive nature, making the development of reliable gas sensors for its detection vital. This study investigated the enhancement in H
2
S gas sensing performance of commercial SnO
2
powders after high-energy milling. SnO
2
powders were subjected to high-energy.....

DOI:
https://doi.org/10.3365/KJMM.2022.60.7.545
Abstract
This study investigated the photovoltaic properties and microstructure of perovskite solar cells (PSCs) with an ITO/SnO
2
/perovskite/HTL/Au electrode configuration, developed with varying sintering temperatures (100~200°C). The goal was to use SnO
2
ink as the electron transport layer (ETL) by low-temperature sintering. TGA-DTA analysis was conducted to determine the optimum sintering temperature.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.11.732
Abstract
To attain high life standards, it is important to develop high-performance non-toxic gas sensors for public safety, environmental pollutant control, industrial processes, etc. Because reports on single element semiconductor-coated semiconducting metal oxides for sensing applications are rare, we synthesized SnO
2
nanowires and coated them with a 5 nm-thick or 10.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.5.384
Abstract
The methane reduction (MR) of SnO
2
has been proposed as a highly efficient method for recovering Sn from SnO
2
containing industrial wastes. The MR of SnO
2
also produces a mixture of H
2
and CO, which can be further utilized as a syngas for the production of various fuels through the.....
