“…With these mild synthesis requirements, significant control both in morphology and chemical modification of the surface can be achieved, which will be useful in designing device architectures ideal for enhancing the surface effects. Extensive morphological control of TI nanostructures has been demonstrated using synthetic chemistry, such as nanoribbons [75], nanorods [65], nanowires [66], nanotubes [74], nanoplates [77], nanorings [75], nanospheres [78], and quantum dots [79]. The crystalline quality of the chemically synthesized TI nanomaterials is high (Fig.…”

1 Introduction Topological insulators (TIs) are recently discovered quantum materials that are insulating in the bulk, but conductive on the surface [1][2][3]. Gapless surface states in TIs originate from strong spin-orbit coupling in the bulk, and exhibit special electronic property of spinmomentum locking due to time reversal symmetry. The exotic electronic nature of the TI surface states has garnered intense interests in this new class of materials and can be used to study several fundamental physical phenomena inaccessible in ordinary materials. The spinmomentum locking property of the TI surface states will undoubtedly be useful for a broad range of future electronic applications such as dissipationless transport, spintronics, and quantum computing.In this review, we follow the recent experimental research progress in TI nanostructures, and discuss various nanomaterial synthesis methods and notable transport measurements. Also, current materials challenges that hinder the easy access and control of the TI surface states are identified and unique solutions that TI nanostructures can provide to overcome these challenges are suggested.

“…The microwave synthesis, which is generally quite fast, simple and efficient in energy, has been developed and is widely used in the fields such as molecular sieve preparation [32,33], radiopharmaceuticals [34,35], the preparation of inorganic complexes and oxide [36][37][38], organic reactions [39][40][41], plasma chemistry [42], analytical chemistry [43], and catalysis [44]. The applications of microwave irradiation in the preparation of nanocrystalline particles have been reported in recent years [45][46][47][48][49][50][51][52]. Microwave irradiation has shown very rapid growth in its application to materials science due to its unique reaction effects such as rapid volumetric heating and the consequent dramatic increase in reaction rates, etc.…”

“…Different solvents possess different dielectric constants, therefore the collision frequency among the molecules and heat speed is different under microwave irradiation. The particle size and shape can be controlled by using different solvents [21,22]. A series of works has proved that the microwave irradiation during aging process has a great benefit to the activity and stability of catalysts.…”

Cu/ZnO/Al 2 O 3 catalysts with Cu/Zn/Al ratios of 6/3/1 were precipitated and aged by conventional and microwave heating methods and tested in the slurry phase reactor for methanol synthesis. The effect of technological condition of precipitation and aging process under microwave irradiation on the catalytic performance was investigated to optimize the preparing condition of Cu/ ZnO/Al 2 O 3 catalyst. The results showed that the microwave irradiation during precipitation process could improve the activity of the catalyst, but had little effect on the stability. While the microwave irradiation during aging process has a great benefit to both the activity and stability of the catalyst, the catalyst aged at 80°C for 1 h under microwave irradiation possessed higher methanol space time yield (STY) and more stable catalytic activity. The activity and stability of the catalyst was further enhanced when microwave irradiation was used in both precipitation and aging processes; the optimized condition for the catalyst precursor preparation was precipitation at 60°C and aging at 80°C under microwave irradiation.
