The highly selective detection of trace gases using transparent sensors at room temperature remains challenging. Herein, transparent nanopatterned chemiresistors composed of aligned 1D Au–SnO2 nanofibers, which can detect toxic NO2 gas at room temperature under visible light illumination is reported. Ten straight Au–SnO2 nanofibers are patterned on a glass substrate with transparent electrodes assisted...
In article number 2100438, Jong‐Heun Lee and co‐workers report transparent gas sensors composed of aligned one‐dimensional Au–SnO2 nanofibers with extremely low coverage, transparent electrode, and glass substrate, which can detect harmful NO2 at room temperature under visible light illumination or natural sunlight. The transparent sensor design enables the unnoticeable installation of gas sensors...
Water poisoning, the dependence of gas‐sensing characteristics on moisture, in oxide chemiresistors remains a long‐standing challenge. Various approaches are explored to mitigate water poisoning but they are often accompanied by significant deterioration of sensing capabilities such as gas response deterioration, gas selectivity alteration, and sensor resistance increase up to unmeasurable levels...
In article number 2007895, Jong‐Heun Lee and co‐workers show that the coating of a moisture‐blocking Tb4O7 overlayer provides a general and facile solution to mitigate the water poisoning effect of oxide semiconductor gas sensors without significant alteration of the gas‐sensing characteristics such as gas response, selectivity, and sensor resistance, enabling the design of reliable gas sensors and...
