Abstract: Disclosed are a zirconium-based metal-organic framework material and a preparation method thereof. Plasma-activated water or strong acid electrolyzed water is added to a raw material system for preparing a zirconium-based metal-organic framework material UiO-66, and they are then subjected to a reaction to obtain a crude product. The crude product is subjected to a post-treatment to obtain the zirconium-based metal-organic framework material UiO-66.

Abstract: A preparation method for a nanopore starch-based adsorbent. The method mainly comprises: constructing a large number of lamellar crystals on surfaces of starch granules, and inducing the formation of a nano-scale pore channel structure by means of the lamellar crystals. A large number of control tests have proved that the flaky crystals have direct influence on the formation of the nano-scale pore channel structure. The construction of a pore channel structure in a starch matrix material greatly increases the specific surface area, and improves the adsorption properties. In addition, the method is beneficial to the introduction of functional particles (magnetic particles), and avoids the problem of pore channel blockage due to first forming pores and then introducing functional particles.

Abstract: The present disclosure discloses a preparation method of porous starch for encapsulating probiotic, and belongs to the field of food processing. The present disclosure provides porous starch with controllable pore size and morphology by regulating the ratio of amylose to amylopectin (quantitative compounding), keeping starch hydroxyl sites exposed (concentration cultivation), and building interfacial tension to stretch starch chains (convection drying), and uses the porous starch to encapsulate probiotics, which can improve the retention rate of probiotics, reduce the loss of probiotics during food processing and transportation, and thus retain the biological functions of probiotics to a maximum extent.

Abstract: The present invention discloses an ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, which comprises a vessel and a plurality of hydrogen production units arranged in the vessel. The hydrogen production unit comprises a cavity, and a broadband ultrasonic generator and a circular hydrogen production electrode located in the cavity. The circular hydrogen production electrode wraps around the broadband ultrasonic generator. A bottom membrane at the bottom of the cavity is hydrophobic at the inner side and hydrophilic at the outer side, and a side membrane of the cavity is hydrophilic at the inner side and hydrophobic at the outer side and is mounted vertically or obliquely upwards by an angle of 0-45 degrees. The system has the functions of continuously and efficiently facilitating self-circulation micro-flow of a liquid system, hydrogen dissolution (as nano-bubbles), conversion from the interface to the bulk phase and dispersion of bubbles, sterilization and others.
