This invention belongs to the field of catalyst materials technology, specifically relating to a Pd-UiO-66 particle electrode, its preparation method, and its application. The Pd-UiO-66 particle electrode uses a zirconium-based metal-organic framework UiO66 as a support. Palladium nanoparticles are obtained by reducing palladium salts with sodium borohydride. The palladium nanoparticles are then reacted with the hydroxyl groups on the polyvinyl alcohol molecules. 2+ The coordination between the components and the steric hindrance effect of the long-chain molecules of polyvinyl alcohol regulate the dispersion of palladium nanoparticles, allowing palladium nanoparticles to be loaded onto UiO66 to obtain Pd-UiO-66. The Pd-UiO-66 particle cathode in this invention avoids the aggregation of palladium nanoparticles, greatly increasing the electrode area / solution volume ratio and helping to provide more active sites for dechlorination.

The utility model discloses a meat duck ecological breeding shed which comprises a duck shed, a partition plate is fixed to the lower portion of the inner side of the duck shed, and a plurality of grating plates are laid on the partition plate. According to the utility model, the servo motor is started to work, so that the main shaft fixed at the output end of the servo motor respectively drives the first transmission belt and the second transmission belt to rotate, the first transmission belt is connected with the left shaft with the exhaust impeller in a winding manner, and the second transmission belt is connected with the right shaft with the air inlet impeller in a winding manner; the exhaust impeller in the exhaust hood and the air inlet impeller in the air inlet hood rotate synchronously, the exhaust impeller and the air inlet impeller of the symmetrically-designed impeller with the opposite installation directions are combined, waste gas in the duck shed is extracted through the exhaust hood and exhausted through the air guide pipe, and external fresh air is sucked in through the air inlet hood. Collaborative ventilation of the duck shed is achieved through the same motor, and energy consumption and breeding cost can be reduced.

The utility model discloses a kind of uniform spraying devices of stress-tolerant synergist for stress-tolerant synergist compound fertilizer processing, including mixing bucket and pesticide pump, the mixing bucket is provided with bucket lid, further including feed hopper and dispersion disc;The central position of the bucket lid is rotatably provided with feed hopper, the lower end of the feed hopper extends to the inside of mixing bucket and penetrates bucket lid, the dispersion disc is fixedly arranged at the lower end of feed hopper, and does not jam feed hopper lower end;Bucket lid lower end surface is equipped with sprinkling tray, the pesticide pump is connected sprinkling tray, the sprinkling tray is above dispersion disc, and cover the area between dispersion disc and mixing bucket inner wall.This utility model can spread fertilizer in mixing bucket by setting dispersion disc and sprinkling tray, and in the process of splashing, sprinkling tray is sprayed to the compound fertilizer particles of splashing dispersion, so that each compound fertilizer particle can be sprayed to additive, and additive amount is not missing, can ensure the quality of compound fertilizer.
