The current invention describes the synthesis of heterogeneous composite comprising laponite and heptamolybdate by wetness impregnation method. Different experimental settings were used to carry out the synthesis, including the heptamolybdate ammonium dose (1.5, 1 or 0.5 g), ion exchanger dose tetrabutyl ammonium bromide (0.5, 0.25 or 0.125g), reaction duration (12 or 24h) and calcination temperature (200, 300 and 400 °C) for 2 hours. The optimal synthesis composition of the laponite / molybdate (Lap-Mo) is as follows: 5 g of Lap + 0.5 g of TBA + 1.5 g of heptamolybdate ammonium with reaction duration of 24 h and a calcination temperature of 300 °C for 2 hours under air. The laponite / molybdate composite have been used in an AOP to degrade MB dye in presence of H2O2 as an oxidant under visible light radiation. The AOP experiment have been optimized using RSM based on BBD. Under the optimum conditions: contact time=72 min, [H2O2 / Lap-Mo] wt% ratio= 1.24, dye concentration= 20.95 mg.L-1 pH= 8.3 reaching a 99% of degradation rate.

Indeed, they exhibits a highly degradation rate equal to 96, 90 and 89% for ST, RhB and MO, respectively. Advantageously, the invention intends to promote, profitably, and efficiently dye degradation using the laponite / molybdate composite.

An engineering prediction method for visible light radiation characteristics is proposed. First, for a hypersonic vehicle, a typical state is selected, and thermochemical nonequilibrium flow field calculations are performed. The flow field is sufficiently large to cover all high-temperature flow fields within the observation direction. Then, based on the flow field calculation results, information such as the observation direction, observation field angle, and observation band is set, and the light radiation intensity is calculated using the radiation characteristic engineering prediction method. This invention addresses the problems of low accuracy and difficulty in engineering application of high-temperature gas radiation characteristic prediction in the thermochemical nonequilibrium region by establishing an engineering prediction method for high-temperature gas radiation characteristics applicable to the visible light band based on thermochemical nonequilibrium flow fields.

A controllable flower-like BSO photocatalyst with nanosheet stacking and its preparation method are disclosed. The method involves improving and controlling the growth of bismuth silicate by introducing CTAB and CTAC to construct a heterogeneous photocatalyst with controllable band gap and morphology. The addition of CTAC reduces the particle size of the sheet-like powder and decreases its packing density, while the addition of CTAB promotes the formation of a flower-like structure. Combined with the synergistic effect of the two dispersants, BSO is modified to control the formation of the heterogeneous structure, resulting in a controllable flower-like structure with thin sheet stacking. This effectively increases the surface area and significantly improves the absorption rate of visible light radiation. The method is simple to operate, and the prepared powder has a uniform particle size distribution and good dispersibility. The resulting composite material not only incorporates the effects of the new heterostructure, but the smaller and thinner sheet-like structure also provides more active sites, exhibiting higher photocatalytic performance. This photocatalyst also has broad applicability to antibiotics and is recyclable.
