Acetic acid (CH3COOH) detection with high selectivity at low temperatures is significant due to its wide applications in the chemical, medical, and catering industries. Chemiresistive gas sensors based on metal oxide semiconductors (MOSs) are widely used in detecting various gases, but it is necessary to develop MOSs with novel nanostructures to enhance gas‐sensing performance. Herein, a series of...
Methane (CH4), as the vital energy resource and industrial chemicals, is highly flammable and explosive for concentrations above the explosive limit, triggering potential risks to personal and production safety. Therefore, exploiting smart gas sensors for real‐time monitoring of CH4 becomes extremely important. Herein, the Pt‐Pd nanoalloy functionalized mesoporous SnO2 microspheres (Pt‐Pd/SnO2) were synthesized,...
Inorganic hollow spheres have wide, important applications due to their unique structure, controllable morphology, and composition. Recent developments in the application and performance of inorganic hollow spheres in solar cells, UV photodectors, gas sensors, and supercapacitors are discussed. For each inorganic hollow sphere based device, a critical comment is given based on knowledge and related...
