“…The accumulation of microbial metabolites in food is usually accompanied by variation in the pH of the food and its micro‐environment (Bhargava et al ., 2020; Azman et al ., 2022). The variation in pH can be monitored by a costly pH‐detector that is based on an electrochemical potentiometer with pH‐detecting electrodes attached to it (Sobhan et al ., 2021; Xu et al ., 2022; Choi et al ., 2023). Recently, pH‐responsive pigments have emerged as a simple tracking technique for pH change in food.…”

SummaryRecently, the assimilation of pH‐sensitive natural pigments into biopolymers has shown promising prospects for pH‐reactive based smart packaging material. Unlike synthetic pigments, which have potential safety problems due to migration, natural pigments have negligible toxicity levels both to humans and the environment and some even possess nutritional and pharmacological properties. To complement the advantages of natural pigments, natural biopolymers have proven to be ideal candidates for the development of smart packaging because of their biocompatibility, availability, biodegradability, stability, minimum toxicity and good film‐forming capability. Smart packaging gives consumers real‐time signals on the quality of packaged food via food deterioration indicators like pH alteration. This review will consider the recent progress in the development of pH‐responsive smart packaging based on natural pH‐sensitive pigments and natural biopolymers from 2013 to the present. It will further discuss the challenges and opportunities of colorimetric smart packaging.

“…Another factor contributing to the poor stability of hybrid SC photocatalysts is their sensitivity to environmental factors such as temperature, humidity, and pH. [ 203 ] Exposure to high temperatures, humidity, or acidic/basic conditions can change the material's structure, composition, and properties, impacting its photocatalytic activity and stability.…”

The degradation of fossil fuel and worse environmental conditions leads to the emergence of hybrid semiconductor (SC) nanomaterials as photocatalysts. Hybrid SCs have interesting physical, mechanical, optical, chemical, and electronic characteristics. Due to these properties’ absorption of light and transfer of charge takes place frequently and hence act as multifunctional surface. These materials should be attributed to their optical and electrical properties and act as multifunctional surfaces in energy production, fuel generation, environmental remediation, sensing, etc. When SCs combine with noble, non‐noble metal, metal oxide, and some carbon‐based materials, they explore wide applications in various fields. Photocatalysis is an effective and sustainable technology to reduce or fix energy concerns and environmental corrosion problems. By going through the extensive literature review, few topics are focused on designing and working mechanisms of hybrid materials. In this way, the present review article explains the properties, surface‐interface engineering, design, and applications (energy and environmental) of hybrid nanomaterials, emphasizing their photocatalytic nature. Additionally, the appealing directions, scientific challenges, and the reasons behind the poor stability of Hybrid SC photocatalyst nanomaterials for energy and environmental applications are discussed. Finally, the concluding remarks and the current challenges with future prospects in this domain are highlighted.

The term “smart materials” can be used to refer a wide variety of different kinds of substances. One capacity that is shared by all of them is the capability to radically alter one or more aspects while operating inside carefully controlled conditions. The age of intelligent materials is arrived, and we are living in it right now. An older definition of smart material described it as a substance that responds swiftly to the environment in which it is located. It has been argued that the word “smart material” now refers to any substance that is capable of detecting, transmitting, or processing a stimulus in order to produce a beneficial effect. This idea has been put forward as a possible expansion of the original meaning of the term. The purpose of this research is to define and categorize different types of intelligent materials. Uses of smart materials are being contemplated in a wide variety of domains, spanning from the realm of technology to that of the modern environment.
