Carbon monoxide binding states over SnO2 and Pt(l%)/SnO2 [PDF]

open access: yes, 1990
1122-1124Carbon monoxide binding states on SnO2 and Pt/SnO2 have been investigated using thermal desorption spectroscopy(TDS). A fourier transform infrared spectrophotometer is attached with TDS for simultaneous analysis of evolved gases.

Fabrication of Microfibre-nanowire Junction Arrays of ZnO/SnO2 Composite by the Carbothermal Evaporation Method

open access: yes, 2014
A cotton-like ZnO/SnO2 nanocomposite was grown by the carbothermal evaporation of a mixture of ZnO and SnO2 powders at 1100oC by the vapour-liquid- solid process, in which the Sn particles produced by the reduction of SnO2 act as the catalyst.

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Pd-SnO2/Al2O3 heteroaggregate nanocatalysts for selective hydrogenations of p-nitroacetophenone and p-nitrobenzaldehyde

open access: yes, 2018
Pd-SnO2 heteroaggregate nanocatalysts were synthesized by in-situ transformation of PdSn bimetallic nano particles on alumina. The PdSn bimetallic nanoparticles were prepared by co-reduction of Pd and Sn precursors.

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

open access: yesAdvanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

open access: yesAdvanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Individual SnO2 nanowire transistors fabricated by the gold microwire mask method

open access: yes, 2009
A gold microwire mask method is developed for the fabrication of transistors based on single lightly Sb-doped SnO2 nanowires. Damage of the nanowire's surface can be avoided without any thermal annealing and surface modification, which is very convenient
