    摘要: This invention relates to a visible-light-responsive photocatalyst for photocatalyticly oxidation desulphurization and method for preparation and application thereof. The catalyst is comprised of one type of metal MI, one type of metal oxide MIIOx and BiVO4 as the supporter, wherein the mass ratio of the sum of the two types of metal (MI+MII) to BiVO4 is from 1:5000 to 1:50; the mass ratio of the type of metal MI to the type of metal MII is from 1:50 to 50:1. The catalyst is used in the photocatalytic oxidation desulphurization. Under mild condition (room temperature, 1 atm), using O2 as the oxidant and xenon lamp (wavelength 420 nm

    摘要: A controller for controlling power to a light source includes a first sensing pin, a second sensing pin, a third sensing pin, and a driving pin. The first sensing pin receives a first signal indicating an instant current flowing through an energy storage element. The second sensing pin receives a second signal indicating an average current flowing through the energy storage element. The third sensing pin receives a third signal indicating whether the instant current decreases to a predetermined current level. The driving pin provides a driving signal to a switch to control an average current flowing through the light source to a target current level. The driving signal is generated based on one or more signals selected from the first signal, the second signal and the third signal.
