Considerable efforts have been dutiful to bimetallic nanomaterials with various architectures due to their interest from both scientific and technological outlooks for the modification of physical and chemical properties of metal nanomaterials. Bimetallic colloids will exhibit function towards environment and biomedical catalyst, but they are distinct from those of the corresponding monometallic nanomaterials. Many methods for the preparation of bimetallic nanomaterials have been reported, such as alcohol and citrate reduction, hydrothermal, sonochemical method, coprecipitation, reverse micelles, and biosynthesis. Consequently, the biosynthesis of metal nanomaterials has been explored as an alternative to developing environmentally benign procedures. Alternatives for the synthesis of bimetallic nanomaterials are currently explored through bacteria, plant biomass, live plants, and their extracts. The catalytic property of metal nanomaterials is also of great interest because of their particle size.

In this special issue, we invite interested scientists to submit original research articles as well as review articles that will stimulate the continuing efforts in order to understand various methods to construct bimetallic nanomaterials and their mechanistic study. Due to its focus towards mechanistic studies, photocatalytic degradation, biomedicine, and catalytic application in organic reaction, we are particularly interested in articles describing novel bimetallic nanomaterials design and application. Potential topics include, but are not limited to:

• Synthesis (biosynthesis) and application of bimetallic metal nanomaterials
• Mechanistic studies toward the green synthesis of bimetallic metal nanomaterials
• Bimetallic nanomaterials: Catalytic activity towards organic synthesis
• Green synthesis of transition bimetallic nanostructures formation for environmental applications
• Developments in bimetallic nanosized photocatalysts
• Synthesis of biocompatible bimetallic nanomaterials
