Semiconducting metal oxide based gas sensors are a highly attractive option for use in a
widespread array of applications as they can be miniaturized, are highly robust and …

Metal oxide gas sensors have long faced the challenge of low response and poor selectivity,
especially at room temperature (RT). Herein, a synergistic effect of electron scattering and …

Detection of volatile organic compounds (VOCs) at room temperature (RT) currently remains
a challenge for metal oxide semiconductor (MOS) gas sensors. Herein, for the first time, we …

Oxygen vacancy (VO), the most common type of defect in metal oxides, could alter intrinsic
properties which are usually determined by crystal structures. Oxygen-deficient metal oxides …

Heterostructured oxides with versatile active sites, as a class of efficient catalysts for CO2
electrochemical reduction (CO2ER), are prone to undergo structure reconstruction under …

Liquid metal‐based printing techniques are emerging as an exemplary platform for
harvesting non‐layered 2D materials with a thickness down to a few nanometres, leading to …

Electronic structure in principle determines the light absorbance, charge transfer and
separation, and consequently, photocatalytic property of a photocatalyst. Herein, we report …

Tin dioxide (SnO2) is a material of ever increasing scientific interest as a result of its many
useful and varied physical properties: it is a wide band gap (3.6 eV at 300 K), n-type …

A series of Ce x Sn 1–x O 2 mixed oxides and single oxides (CeO 2 and SnO 2) were
prepared by inverse co-precipitation method and calcined at 450 and 750° C to investigate …
