The invention relates to a glucose carbonization synergistically modified SrTiO3 photocatalyst as well as a preparation method and application thereof, and belongs to the technical field of photocatalytic materials. The preparation method comprises the following steps: firstly, preparing an SrTiO3 matrix by taking molten salt as a medium through a high-temperature solid-phase method; and mixing SrTiO3 with glucose, and carrying out low-temperature calcination to realize doping of carbon ions and construction of a surface carbon layer so as to obtain the target photocatalyst. The catalyst can be widely applied to the field of photocatalytic full water splitting. The prepared catalyst has the remarkable advantages that the forbidden band width of SrTiO3 is effectively narrowed, and the visible light absorption range of SrTiO3 is expanded; and the surface carbon layer has the characteristics of an electron conductor, so that the migration of photo-induced electrons to reaction sites can be accelerated, and the carrier separation efficiency is greatly improved. The preparation method disclosed by the invention is green and environment-friendly, simple in steps, convenient to operate and low in material cost, conforms to the current green development concept, and has a wide application prospect in the field of new energy such as photocatalytic hydrogen production.

The application discloses a kind of furnace tube ash removal agent. It is constituted by the following components by weight fraction: 10-30 parts of composite inorganic salt, 10-30 parts of composite mineral aggregate, 5-10 parts of alkaline substance, 1-3 parts of catalyst, 3-8 parts of accelerator, 3-5 parts of corrosion inhibitor, 100-200 parts of water. The furnace tube ash removal agent of the application has the effect of removing hard ash, which forms a low-melting eutectic with the hard scale on the pipe wall, so that the hard ash becomes a loose and easily peeled product and falls off by itself; reduces carbon ion emission and improves combustion efficiency; while removing ash, a protective film is formed on the surface of the furnace tube, which also inhibits the deposition of ash; ash can be removed online without stopping production; eliminates dust pollution and its impact on the respiratory system, which is beneficial to environmental protection.

The application provides a waste plastic hydrogenation catalytic cracking oil refining method and application. The catalyst carrier is ZSM-5 molecular sieve, and the active center loaded is a transition metal; in a hydrogen atmosphere, a high-temperature static cracking process of plastic and catalyst mixing. The reaction of polyethylene on the catalyst loaded with transition metal follows the carbon ion theory and the free radical catalytic pyrolysis. The ZSM-5 molecular sieve provides protons for the reaction, the protons are combined with polyethylene and then short chain olefins are generated through the carbon ion theory. However, due to the too large molecule, the polyethylene cannot directly enter the inside of the ZSM-5 molecular sieve channel, so the molten polyethylene will first react under the catalysis of the active center on the surface, depolymerize into products with small molecular weight, then enter the channel to react, and after entering the inside of the channel, secondary reactions such as beta-scission, isomerization, aromatic ring formation and the like occur. The method can relatively safely and environmentally protect convert the plastic into crude oil, the reaction temperature is low, and the catalyst effect is remarkable.

A substrate processing tool capable of forming an carbon layer on a substrate by generating a plasma including carbon and non-carbon ions in a processing chamber, suspending the carbon and non-carbon ions in the processing chamber, removing mostly the suspended non-carbon ions from the processing chamber, and bombarding the substrate surface with mostly carbon ions. The one or more steps of the above sequence may be repeated until the carbon layer is of desired thickness.

In a laser-driven ion acceleration type carbon ion generating device, generation of impurity ions is suppressed. A carbon ion generating device (10) irradiates a first laser beam (laser beam L1) to a thin film (21) of an organic compound, i.e., a thin film, to generate a carbonized region (22), and irradiates a second laser beam (laser beam L2) to at least a part of the carbonized region (22) to generate carbon ions.
