The influence of the number of operating parameters on photocatalytic and sonocatalytic Acid Red 88 degradation from an aqueous solution was investigated in this paper. The experimental results indicated that the sonocatalytic process with Ni-TiO2 was far more effective for the degradation of high concentration azo dyes, regardless of the process condition. In order to achieve a larger surface ...

Developing the large-scale preparation of non-noble metal catalysts with high performance is crucial for promoting electrochemical production hydrogen from water. In this work, a novel TiO2@FeNi2S4 (TiO2@FNS) branch nanoflake array on Ni foam can be prepared at large scale (50 cm2) by combining an atomic-layer-deposited (ALD) TiO2 skeleton one-step facile low-temperature (<100 °C) sulfurizat...

Nanoreactors are material structures that provide engineered internal cavities that create unique confined nanoscale environments for chemical reactions. Crumpled graphene nanoparticles or "nanosacks" may serve as nanoreactors when filled with reactive or catalytic particles and engineered for a specific chemical function. This article explores the behavior of crumpled graphene nanoreactors con...

Nanometer TiO2 photocatalysts were prepared by the sol–gel method. The catalysts characterized X-ray diffraction, Fourier-transform infrared spectroscopy, ultraviolet-visible and other techniques. Methyl orange solution was used for degradation of organic material ultrasonic technology to determine photocatalytic performance catalysts. results show that Ni-N-TiO2 is clearly improved under condi...

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the incre...
