A novel PTA/ZIF‐8@CA composite material (PTA = phosphotungstic acid; CA = cellulose aerogel) with multilayer three‐dimensional network structure was synthesized with cellulose aerogel as the framework and MOFs as the filler. The results showed that the degradation rates of methylene blue at δ = 10 ppm reached 99.8 % respectively in 30 min under the conditions of PTA/ZIF‐8@CA input amount of 0.6 g·L–1 and pH = 5. The degradation rate of rhodamine B at δ = 10 ppm reached 99.7 % in 60 min. This shows that PTA/ZIF‐8@CA has excellent degradation efficiency and short‐term performance. In addition, after 5 photocatalytic cycles, the degradation rates of methylene blue and rhodamine B by PTA/ZIF‐8@CA were still 83.0 % and 82.5 %, respectively, reflecting that PTA/ZIF‐8@CA has terrific photocatalysis stability.

Oxygen evolution reaction (OER) plays a vital role in fuel cells, water splitting and metal-air batteries. Efficient electrocatalysts could overcome the higher overpotential of OER, improve electron transfer efficiency, and...

Designing a humidity sensor with high performance to quick and accurate detect relative humidity (RH) is important in various applications. Consideration must be given to both the high response and the quick reversibility. Here, based on Quartz Crystal Microbalance (QCM) sensing platform, we utilized commercial graphene oxide as a sensing material, and added commercial carbon nanocoil to block the
