The One

The aggregation and the rapid restructuring of the photoinduced electron−hole pairs restructuring in the process of photoelectric response remains a great challenge. In this study, a kind of Multi-walled carbon nanotubes loaded Alpha-Fe2O3 (CNTs/α-Fe2O3) heterostructure composite is successfully prepared via the one-step method. Due to the synergistic effect in the as-prepared CNTs/α-Fe2O3, the defect sites and oxygen-containing functional groups of CNTs can dramatically improve the interface charge separation efficiency and prevent the aggregation of α-Fe2O3. The improved photocurrent and enhanced hole–electron separation rate in the CNTs/α-Fe2O3 is obtained, and the narrower band gap is measured to be 2.8 ev with intensive visible-light absorption performance. Thus, the CNTs/α-Fe2O3 composite serves as an excellent visible light photocatalyst and exhibits an outstanding photocatalytic activity for the cationic dye degradation of rhodamine B (RhB). This research supplies a fresh application area forα-Fe2O3 photocatalyst and initiates a new approach for design of high efficiency photocatalytic materials.

Self Cleaning

This research intends to enhance the photocatalytic efficiency and durability of substrates coated with TiO2-based nanocomposites under visible light illumination. More specifically, TiO2/SiO2/graphene oxide nanocomposites are successfully sono-synthesized and sono-fabricated onto a polymeric fabric through a facile one-step method. The morphologies, phase structures and optical properties of the samples are studied. The photocatalytic activity of the functionalized samples is assessed through a gentian violet stain removal test and then photodecomposition of methylene blue under visible light, and tested again after 10 washes to check on its durability. It is corroborated that TiO2/SiO2/graphene oxide nanocomposites have shown significantly better visible light self-cleaning performance than just using the pure TiO2 alone. In addition, even after 10 washes, the samples virtually maintain the functionality. Herein, sono-synthesis of TiO2/SiO2/graphene oxide represents a remarkable step forward in visible light-driven self-cleaning treatment for flexible materials and, hence, holds a great potential for commercialization.

Dynamic Curing

The effect of dynamic curing of PP/EPDM blends with sulfur and thiuram disulfide systems on their mechanical properties was studied. The results were interpreted using the knowledge of the formation of phase structure in the blends during their melt mixing. It was shown, that a sufficiently slow curing reaction is necessary if a high impact strength is to be obtained. Only in such case, a fine and homogeneous dispersion of elastomer can be formed, which is the necessary condition for high impact strength of the blend. Using an inhibitor of curing in the system and a one-step method of dynamic curing leads to an increase in impact strength of blends. From the comparison of shear modulus and impact strength values, it follows that, at the stiffness, the dynamically cured blends have higher impact strength than the uncured ones.
