    摘要: The present invention provides a biological morph-genetic WO3 photocatalyst and a preparation method and application thereof, and belongs to the technical field of photocatalysis The preparation method of the present invention includes the following steps: impregnating a rice husk into a tungsten source solution, and roasting an obtained solid material after solid-liquid separation to obtain the biological morph-genetic WO3 photocatalyst. The present invention utilizes the rice husk as a biological template agent; the rice husk contains a large amount of silicon dioxide, and has a silicon-carbon network structure; the rice husk is impregnated into the tungsten source solution, and after roasting, a tungsten source replicates the silicon-carbon network structure of the rice husk, forming a hierarchical structure including a micropore and a mesopore with good adsorption; at the same time, during the roasting process, the carbon of the rice husk is doped into a lattice of the WO3, which facilitates transfer between charges in the lattice of the WO3, reduces a forbidden band width of the WO3, and improves the photocatalytic reaction performance of the WO3.

    摘要: A UV treatment cartridge having an exterior housing and a UV treatment module located inside of the exterior housing. The UV treatment module having a UVLED array for UV treatment of a fluid passing through the UV treatment module. An internal annular space between the exterior sidewall and the module sidewall forms an entry flow path to the UV treatment module thereby substantially balancing fluid pressure acting on the inside of the module sidewall and acting on the outside of the module sidewall.

    摘要: A substance treatment apparatus includes an RF signal source, power detection circuitry, a controller, and a transmission path between the RF signal source and a first electrode that radiates electromagnetic energy into a chamber. The RF signal source includes a solid-state amplifier that generates an RF signal. The power detection circuitry detects reflected signal power along the transmission path. Based on the reflected signal power, the controller modifies values of variable components within an impedance matching network electrically coupled along the transmission path to adjust a magnitude of the reflected signal power. The impedance matching network may have a double-ended input connected to a balun, and a double-ended output connected to the first electrode and to a second electrode. Alternatively, the impedance matching network may have a single-ended input connected to the RF signal source, and a single-ended output connected to the first electrode. The second electrode may be grounded.
