Synergy of S-vacancy and heterostructure in BiOCl/BiS boosting room-temperature NO sensing.

The special physicochemical properties of BiS nanomaterial endow it to be exceptional NO sensing properties. However, sensors based on pure BiS cannot detect trace NO at room temperature effectively due to the scanty active sites and poor charge transfer efficiency. Herein, vacancy defect and heterostructure engineering are rationally integrated to explore BiOCl/BiS heterostructure with rich S vacancies to enhance NO sensing performance.

Corrosion Behavior of High-Cr-Ni Materials in Biomass Incineration Atmospheres.

In this paper, the corrosion test of high-Cr-Ni tubes was carried out in a biomass incinerator by replacing the original heated surface tube with a test tube. The investigated materials are high-Cr-Ni stainless steels (TP347H, SP2215, and Sanicro25) and alloy (HT700T). Long-term services (>4000 h) to investigate the corrosion rates and corrosion characteristics of the materials have been carried out.
