A series of Zn-modified nano-HZSM-5 (Zn/NZ) zeolite catalysts were prepared and used in the conversion of methanol to light aromatics (benzene, toluene, and xylene; BTX). The reaction conditions and loading of Zn exhibited a significant influence on the BTX yield. The interaction of Zn species with hydroxyl groups (OH) occurred on the HZSM-5 surface with the loading of Zn on a HZSM-5 zeolite. Such interaction distinctly changed the texture and acidity of the Zn/HZSM-5 catalyst. On the other hand, reduction of the Zn/NZ crystal size not only improved the interaction of the Zn species with HZSM-5 but also enhanced the resistance of coke deposition. The high BTX yield of 67.7% and good catalytic stability were obtained on a 0.5 wt % Zn/NZ catalyst, mainly because of its proper concentration and distribution of acid sites as well as the small crystal size with improved physical transport.

In the cutting-edge field of cancer therapy, noninvasive photothermal therapy (PTT) has received great attention because it is considered to overcome the drawbacks of conventional surgery, radiotherapy and chemotherapy of severe body injuries and side effects on the immune system. The construction of PTT therapeutic and theranostic nanoplatforms is the key issue in achieving tumor targeting, imaging and therapy in a synergetic manner. In this review, we focus on the recent advances in constructing PTT therapeutic and theranostic nanoplatforms by integrating nanomaterials and functional polymers. The noninvasive photothermal cancer therapy mechanism and achievement strategies of PTT therapeutic and theranostic nanoplatforms are presented as well as the innovative construction strategies and perspectives for the future. Owing to their high tumor ablation efficiency, biological availability and low- or non-toxicity, PTT therapeutic and theranostic nanoplatforms are promising and emerging in medicine and clinical applications.

A facile process is developed to prepare SnO-based composites through using metal-organic frameworks (MOFs) as precursors. The nitrogen-doped graphene wrapped okra-like SnO composites (SnO@N-RGO) are successfully synthesized for the first time by using Sn-based metal-organic frameworks (Sn-MOF) as precursors. When utilized as an anode material for lithium-ion batteries, the SnO@N-RGO composites possess a remarkably superior reversible capacity of 1041 mA h g at a constant current of 200 mA g after 180 charge-discharge processes and excellent rate capability. The excellent performance can be primarily ascribed to the unique structure of 1D okra-like SnO in SnO@N-RGO which are actually composed of a great number of SnO primary crystallites and numerous well-defined internal voids, can effectively alleviate the huge volume change of SnO, and facilitate the transport and storage of lithium ions. Besides, the structural stability acquires further improvement when the okra-like SnO are wrapped by N-doped graphene. Similarly, this synthetic strategy can be employed to synthesize other high-capacity metal-oxide-based composites starting from various metal-organic frameworks, exhibiting promising application in novel electrode material field of lithium-ion batteries.
