The invention relates to a multifunctional composite material with a heterostructure as well as a preparation method and application of the multifunctional composite material with the heterostructure, and belongs to the technical field of photocatalysis. The preparation method comprises the following steps of: dissolving an graphene oxide in water, carrying out ultrasonic processing to obtain a graphene oxide dispersion liquid, and dripping a silver nitrate solution into the graphene oxide dispersion liquid while stirring, so as to obtain a mixed solution A; slowly dripping ammonia water into the mixed solution A to obtain a mixed solution B; stirring the mixed solution B, and slowly dripping a disodium hydrogen phosphate solution into the mixed solution B to obtain a mixed solution C; then slowly dripping a P25 solution into the mixed solution C under the magnetic stirring condition to be continuously stirred, transferring the obtained mixed solution C into a hydrothermal reaction kettle, and cooling the obtained mixed solution C till the temperature of the obtained mixed solution C drops to the room temperature after the hydrothermal reaction; and carrying out the vacuum drying on a resultant to obtain a composite material after the resultant is centrifuged and rinsed. The prepared composite material can not only absorb pollutants in water, but can also rapidly degrade organic pollutants of certain concentration under the irradiation of visible light. Moreover, the prepared composite material has efficient broad spectrum sterilization activity to various common bacteria.

A cover-type containing structure for flexible enclosures primarily includes a front cover sheet, a rear cover sheet and a flexible enclosure. The front cover sheet includes a first joining edge and a cover piece, whereas the rear cover sheet includes a cover assembly corresponding to the cover piece. The flexible enclosure includes a second joining edge and by engaging the first joining edge with the second joining edge, the front cover sheet and the flexible enclosure are fixed. Besides, the containing structure further includes a holding portion. Under a contained state, the holding portion is used to contain smaller objectives; whereas, in an unfolded state, in addition to using the flexible enclosure to contain larger objectives, the holding portion can be also used to contain smaller objectives. The present invention can be also applied to a piece of clothing combined with a bag unit or other flexible enclosure.

Disclosed are embodiments related to chip pressing devices. One such chip pressing device includes a bottom portion and a top portion, which is configured to be attached to or separated from the bottom portion, and has a compartment portion, an upper chamber, and a lower chamber, wherein the upper chamber is spaced apart from the lower chamber by the compartment portion. The upper chamber has one or more gas passages, the lower chamber has one or more gas inlets and one or more gas outlets, and the compartment portion has one or more through-holes. One or more pressing heads movably fit into the through-holes; one or more gas pressure sources connected to at least one of the gas passages of the upper chamber, wherein the upper chamber is pressurized, and one or more heated gas sources are connected to the one or more gas inlets of the lower chamber.
