Abstract
The development of chemical sensors is an urgent need for both environmental and health issues. The breakthrough needed for the advancement of these devices is the development of efficient receptors. Porphyrins have been widely used as sensing layers in chemical sensors, but their integration with nanostructures can greatly boost the performance of these macrocycles, improving from one side the stability of the sensing layer, and from the other, offering additional interaction mechanisms with target analytes. We present here some recent examples of hybrid materials prepared by the integration of porphyrins with metal and metal oxide nanoparticles, porphyrin-based metal organic frameworks and their exploitation as sensing layers in chemical sensors.

Abstract
A non-enzymatic amperometric sensor using natural molybdenite (MLN) electrodeposited with methylene blue (MB) has been fabricated and characterized and its analytical performances were investigated for the determination of ascorbic acid (AA). The surface morphology of the electrode modified by electrodeposited MB was studied by use of the Advanced Mineral Identification and Characterization System (AMICS) and laser confocal high-temperature scanning microscope (LCSM). The poly(MB) and MLN immobilized sensor showed good stability, reproducibility, sensitivity, and selectivity. It exhibited a linear performance range from 3 to 1000 μM, with a lower detection limit of 0.083 μM (signal/noise = 3) and short response time (< 5 s). No obvious decrease in the current was observed after 20 days storage. The methodology reproducibility of this sensor was 2.6%. It showed good anti-interference ability for the potential interfering compounds. The poly(MB) film not only can enhance the electron-transfer rate but also increase the lifetime of the sensor. This study demonstrated the applicability of natural molybdenite for the fabrication of non-enzymatic electrochemical AA sensor.

Abstract
In this paper, we synthesized HNbMoO6/C composite through the calcination of octylamine-intercalated HNbMoO6 precursor. The resulting HNbMoO6/C composite showed some new phases of MoO2, MoO3, NbO2, Nb2O5, and carbon, which was fully confirmed via powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and X-ray photoelectron spectroscopy (XPS) technologies. Besides, the HNbMoO6/C hybrid was coated on glass carbon electrode to construct an electrochemical sensor for sensitive determination of clenbuterol. The electrochemical behaviors of clenbuterol on the prepared electrode were tested by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) analysis. The results showed that the intercalated carbon can act as active sites to accelerate electron transfer. In addition, more exposed surface areas of the HNbMoO6/C composite will facilitate the electrolyte to permeate. The oxidation peak current of clenbuterol was linearly related to its concentration in the range of 1.04 × 10-5 to 7.51 × 10-4 mol L-1, and the determination limit was calculated to be 3.03 × 10-6 mol L-1 (S/N = 3). This sensor exhibits excellent stability, reproducibility, specificity, and good recoveries when applied to monitor clenbuterol in real samples.
