Metal–organic frameworks (MOFs) combined with ZnO quantum dots as a fluorescent sensing platform for phosphate

Co3O4 Electrode Prepared by Using Metal‐Organic Framework as a Host for Supercapacitors

“…Metal-organic frameworks (MOFs) have been widely noticed by people due to open pores, steady pore structures, excellent heat stability, and high ordered crystalline state as new porous materials. They become a new trend to the research fields, such as gas separation and preservation, sensors, drug delivery, and heterogeneous catalysis [13][14][15][16]. Bhakta et al demonstrated that MOFs could be employed as effective hosts for nanoscale metal hydride such as NaAlH 4 recently [17].…”

Synthesis of ZnO nanoparticles with a novel combustion method and their C2H5OH gas sensing properties

“…10. At the optimal operating temperature (370 °C), for ethanol gas of a series of concentrations the response time 9 ranged from 10 s to 4 s and the recovery time ranged from 30 s to 39 s, which are very attractive for practical applications.…”

“…In this regard, metal oxide semiconductor (MOS) based gas sensors, such as SnO 2 [3], ZnO [4], TiO 2 [5], WO 3 [6] and In 2 O 3 [7] have been extensively studied because of their great potential applications in toxic and flammable gas detection. As a gas sensing material, ZnO possesses some unique advantages: a bandgap of 3.37 eV, large exciton binding energy of 60 meV, resistivity control over the range 10 −3 ∼10 5 Ω·cm, high transparency in the visible range, excellent chemical and thermal stability under the operating condition, thus ZnO has been widely applied in the field of gas/chemical sensors [8][9], optoelectronics [10], laser diodes [11], piezotronics [12], and field emission devices [13].…”

Metal–organic frameworks assembled from lanthanide and 2,5-pyridinedicaboxylate with cubane-like [Ln4(OH)4] building units

“…Recently, much work has been focused on lanthanide-containing MOFs (LOFs) [14][15][16], because these compounds give rise to luminescence materials [17][18][19][20][21][22][23], with increased brightness and emission quantum yield [24,25], and therefore they could be very promising class of materials in a wide range of optical applications including fluorescent sensing [26][27][28], imaging contrast agents [29,30], and lighting and displays [31]. Many d-block transition metal cations prefer to be coordinated by soft donor atoms, whereas lanthanide cations (Ln 3+ ), with their high and variable coordination numbers and flexible coordination environments, have high affinity for hard donor atoms [32,33], and therefore leading to complex network topologies with promising potential applications.…”
