The present invention provides a preparation method of a photocatalytic composite material, and relates to the field of catalyst technologies. The preparation method provided in the present invention includes the following steps: (1) subjecting plant leaves to soaking pretreatment to obtain template biomass; (2) mixing a molybdenum source-sulfur source aqueous solution with the template biomass obtained in step (1) and conducting impregnation to obtain a composite material precursor; and (3) calcining the composite material precursor obtained in step (2) to obtain the photocatalytic composite material. The photocatalytic composite material in the present invention includes acicular molybdenum sulfide and biomass carbon, the acicular molybdenum sulfide is loaded to a surface of the flake carbon, the mass content of the biomass carbon is 70% to 90%, and the mass content of the molybdenum sulfide is 10% to 30%. Performance of photocatalytic hydrogen production of the photocatalytic composite material in the present invention is better than that of a pure molybdenum sulfide material and has excellent photocorrosion resistance, and hydrogen production efficiency is reduced by only approximately 10% after three cycles.

Photocatalytic composite material and preparation method and application thereof

Examples embodiments of a method and system for synchronizing active illumination pulses in a multi-sensor imager is provided. Example embodiments of the method disclosed herein include the provision of an illumination pulse for each of N sensors, each of N illumination pulses are set to have the same pulse period and active pulse width. Moreover, example embodiments include setting the active width pulse for each of the N illumination pulses to have maximum exposure time for each of N image sensors, and in further examples, ensuring that the time to capture a frame plus the time interval between subsequent image captures is the same for each sensor. In yet further examples, an offset period between subsequent frame synchronous signals is determined. In yet further example embodiments, an interval between frame captures is adjusted and a negative edge of the frame synchronous signal and an illumination pulse is aligned.
